I installed VS 11 beta and SQL Server 2012 on my development machine and at one point, I was asked to upgrade my database from version 661 (SQL Server 2008 R2) to SQL Server 2012.
I clicked yes, continued building, and now I've just realized that the file won't deploy in SQL Server 2008 R2, which is the version installed on the staging server (I don't control that machine).
I've thought of exporting the database to another format (access for instance) and reimporting it in SQL Server 2008 R2. Is that the best way to solve my problem? Is there another better way?
Thanks for your suggestions.
You have at least four options:
Restore your last pre-upgrade backup
Re-create the database from scripts in source control
Use SMO to generate scripts for all objects and re-create the database
Use SSIS or a third-party tool to copy all database objects from one DB to another
If you opt to re-create the database from scripts, you can then use SSIS or bcp to copy the data over. But restoring a backup is by far the easiest solution and if you don't take regular backups of your development environment then this might be a good time to start.
And as someone else advised, do not develop using tools and versions that don't match your production environment.
Look at this 10-minute solution to learn how to recreate your upgraded database using "Generate SQL Server Scripts" wizard.

I know that you can't (at least not easily) restore a SQL Server 2012 backup on SQL Server 2008. But how does it work for SQL Server 2014 to SQL Server 2012 ?
On database level there is the property to adjust the compatibility mode to any other SQL Server version.
How does this helps or work ? Will it only disallow the features from 2014?
To be honest I already tried to restore a backup, but 2012 didn't recognize the datafile, so I couldn't click ok Button to start the restore procedure.
Did I miss some important option ?
You CANNOT do this - you cannot attach/detach or backup/restore a database from a newer version of SQL Server down to an older version - the internal file structures are just too different to support backwards compatibility. This is still true in SQL Server 2014 - you cannot restore a 2014 backup on anything other than another 2014 box (or something newer).
You can either get around this problem by
using the same version of SQL Server on all your machines - then you can easily backup/restore databases between instances
otherwise you can create the database scripts for both structure (tables, view, stored procedures etc.) and for contents (the actual data contained in the tables) either in SQL Server Management Studio (Tasks > Generate Scripts) or using a third-party tool
or you can use a third-party tool like Red-Gate's SQL Compare and SQL Data Compare to do "diffing" between your source and target, generate update scripts from those differences, and then execute those scripts on the target platform; this works across different SQL Server versions.
The compatibility mode setting just controls what T-SQL features are available to you - which can help to prevent accidentally using new features not available in other servers. But it does NOT change the internal file format for the .mdf files - this is NOT a solution for that particular problem - there is no solution for restoring a backup from a newer version of SQL Server on an older instance.
Sure it's possible... use Export Wizard in source option use SQL SERVER NATIVE CLIENT 11, later your source server ex.192.168.100.65\SQLEXPRESS next step select your new destination server ex.192.168.100.65\SQL2014
Just be sure to be using correct instance and connect each other
Just pay attention in Stored procs must be recompiled
At home, I have SQL Server 2008 R2 (Express) installed which is attached to a certain .mdf file. I'm in the process of installing SQL Server 2012 (Developer Edition). Can I attach 2012 to the same .mdf file? Logically, it seems like this would work as long as only one of the two instances of SQL Server is running. Thoughts?
You can go upwards - from an older version to a newer one, e.g. you can backup your database in 2008 R2 and restore that backup in your 2012 instance - but you CANNOT attach/detach or backup/restore a database from a newer version of SQL Server down to an older version - the internal file structures are just too different to support backwards compatibility.
Also: since the internal file structures of the .mdf are very much different and specific to each version of SQL Server, you will NOT be able to use the same .mdf from two different SQL Server versions. That definitely won't work.

It might work - but I believe you're going run in to some issues later down the road if the SQL 2012 updates the file in a technical manner that SQL 2008 blows up on.
Wouldn't it be simpler to run one copy and back up and restore to the other?
Were there any changes in this area with SQL Server 2014? I’ve seen this post Is it possible to restore Sql Server 2008 backup in sql server 2005 and I know that this was not possible as a scenario for 2012 -> 2008 but I wonder if MS made any changes here with the 2014 version.
We are evaluating 2014 version and we have a fairly large database in testing. We’d like to restore a backup of that database to SQL Server 2008 because that physical machine has more space, RAM,…
I’m getting standard error message when I try to restore backup but I was wondering if there is something else in SQL Server 2014 that I might be missing.
No, it is not possible. Stack Overflow wants me to answer with a longer answer, so I will say no again.
Documentation: https://learn.microsoft.com/en-us/sql/t-sql/statements/backup-transact-sql#compatibility
Backups that are created by more recent version of SQL Server cannot
be restored in earlier versions of SQL Server.
Not really as far as I know but here are couple things you can try.
Third party tools: Create empty database on 2008 instance and use third party tools such as ApexSQL Diff and Data Diff to synchronize schema and tables.
Just use these (or any other on the market such as Red Gate, Idera, Dev Art, there are many similar) in trial mode to get the job done.
Generate scripts: Go to Tasks -> Generate Scripts, select option to script the data too and execute it on 2008 instance. Works just fine but note that script order is something you must be careful about. By default scripts are not ordered to take dependencies into account.
It is a pretty old post, but I just had to do it today. I just right-clicked database from SQL2014 and selected Export Data option and that helped me to move data to SQL2012.
Pretty old question... but I had the same problem today and solved with script, a little bit slow and complex but worked. I did this:
Let's start from the source DB (SQL 2014) right click on the database you would like to backup -> Generate Scripts -> "Script entire database and all database objet" (or u can select only some table if u want) -> the most important step is in the "Set Scripting Options" tab, here you have to click on "Advanced" and look for the option "Script for Server version" and in my case I could select everything from SQL 2005, also pay attention to the option "Types of data to script" I advice "Schema and data" and also Script Triggers and Script Full-text Indexes (if you need, it's false by default) and finally click ok and next. Should look like this:
Now transfer your generated script into your SQL 2008, open it and last Important Step:
You must change mdf and ldf location!!
That's all folks, happy F5!! :D
No I guess you cannot restore the databases from higher version to lower version , you can make data flow b/w them i,e you can scriptout.
http://www.mssqltips.com/sqlservertip/2810/how-to-migrate-a-sql-server-database-to-a-lower-version/
Please use SQL Server Data Tools from SQL Server Integration Services (Transfer Database Task) as here: https://stackoverflow.com/a/27777823/2127493
If you have both versions you can create a merge replication from new to old. Create a merge publication on your newer sql server and a subscription on the older version. After initializing the subscription you can create a backup of the database with the same structure and the same content but in an older version and restore it on your old target server.
You can use this method also with sql server 2016 to target 2014, 2012 or 2008.
How to restore a higher version SQL Server database backup file onto a lower version SQL Server?
Using SQL Server 2008 R2 (10.50.1600), I made a backup file and now I want to restore it on my live server's SQL Server 2008 (10.00.1600).
When I tried to restore the backup onto SQL Server 2008 it gives an error i.e. Restore Failed because:
The database was backed up on a server running version 10.50.1600.
That version is incompatible with this server, which is running version
10.00.1600.
How do I restore the backup file on this server?
You can use functionality called Export Data-Tier Application which generates .bacpac file consisting database schema and data.
On destination server, you can use Import Data-Tier Application option which creates and populates new database from pre-created .bacpac file
If you want just to transfer database schema, you can use Extract Data-Tier Application for creating file and Deploy Data-Tier Application for deploying created database schema.
I've tried this process on different versions of SQL Server from SQL 2014 to SQL 2012 and from SQL 2014 to SQL 2008R2 and worked well.
No, is not possible to downgrade a database. 10.50.1600 is the SQL Server 2008 R2 version. There is absolutely no way you can restore or attach this database to the SQL Server 2008 instance you are trying to restore on (10.00.1600 is SQL Server 2008). Your only options are:
upgrade this instance to SQL Server 2008 R2 or
restore the backup you have on a SQL Server 2008 R2 instance, export all the data and import it on a SQL Server 2008 database.
You can not restore database (or attach) created in the upper version into lower version. The only way is to create a script for all objects and use the script to generate database.
select "Schema and Data" - if you want to Take both the
things in to the Backup script file select Schema Only -
if only schema is needed.
Yes, now you have done with the Create Script with Schema and Data of the Database.
Will not necessarily work
Backup / Restore - will not work when the target is an earlier MS SQL version.
Copy Database - will not work when the target is SQL Server Express: "The destination server cannot be a SQL Server 2005 or later Express instance."
Data import - Will not copy the schema.
Will work
Script generation - Tasks -> Generate Scripts. Make sure you set the desired target SQL Server version on the Set Scripting Options -> Advanced page. You can also choose there whether to copy schema, data, or both. Note that in the generated script, you may need to change the DATA folder for the mdf/ldf files if moving from non-express to express or vice versa.
Microsoft SQL Server Database Publishing Services - comes with SQL Server 2005 and above, I think. Download the latest version from here. Prerequisites: sqlncli.msi/sqlncli_x64.msi/sqlncli_ia64.msi, SQLServer2005_XMO.msi/SQLServer2005_XMO_x64.msi/SQLServer2005_XMO_ia64.msi (download here).
Here are my 2 cents on different options for completing this:
Third party tools: Probably the easiest way to get the job done is to create an empty database on lower version and then use third party tools to read the backup and synchronize new newly created database with the backup.
Red gate is one of the most popular but there are many others like ApexSQL Diff , ApexSQL Data Diff, Adept SQL, Idera …. All of these are premium tools but you can get the job done in trial mode ;)
Generating scripts: as others already mentioned you can always script structure and data using SSMS but you need to take into consideration the order of execution. By default object scripts are not ordered correctly and you’ll have to take care of the dependencies. This may be an issue if database is big and has a lot of objects.
Import and export wizard: This is not an ideal solution as it will not restore all objects but only data tables but you can consider it for quick and dirty fixes when it’s needed.
Another way to do this is to use "Copy Database" feature:
Find by right clicking the source database > "Tasks" > "Copy Database".
You can copy the database to a lower version of SQL Server Instance. This worked for me from a SQL Server 2008 R2 (SP1) - 10.50.2789.0 to Microsoft SQL Server 2008 (SP2) - 10.0.3798.0
You can try this.
Create a Database onto SQL Server 2008.
Using Import Data feature import data from SQL Server R2 (or any higher version).
use "RedGate SQLCompare" to synchronize script.
Go to Task->Generate Scripts...
In Advanced in "Types of data for script" select "Schema and data" and try to run this script in your lower version.
It's not pretty, but this is how I did it granted you have this option installed on your SQL 2008 R2 install..
1) Right click database in SQL Server 2008 R2 "Tasks".. "Generate scripts" in the wizard, select the entire database and objects in first step. On the "Set Scripting Options" step you should see a button "Advanced" , select this and make sure you select "Script for Server Version" = SQL Server 2008" not R2 version.
This is a crucial step, because "import data" by itself does not bring along all the primary keys, constriants and any other objects like stored procedures."
2) Run the SQL script generated on the new install or database instance SQL Express or SQL Server 2008 using the query window or open saved .sql script and execute and you should see the new database.
3) Now right click on the new database and select "Tasks".. "Import Data.." choose source as the R2 database and the destination as the new database. "Copy data from one or more tables or views", select the top checkbox to select all tables and then next step, run the package and you should have everything on a older version. This should work for going back to a 2005 version as well. Hope this helps someone out.
you can use BCP in and out for small tables.
BCP OUT command:-
BCP "SELECT * FROM [Dinesh].[dbo].[Invoices]" QUERYOUT C:\av\Invoices1.txt -S MC0XENTC -T -c -r c:\error.csv
BCP IN command:-
Create table structure for Invoicescopy1.
BCP [Dinesh].[dbo].[Invoicescopy1] IN C:\av\Invoices.txt -S MC0XENTC -T -c
I appreciate this is an old post, but it may be useful for people to know that the Azure Migration Wizard (available on Codeplex - can't link to is as Codeplex is at the moment I'm typing this) will do this easily.
You'd have to use the Import/Export wizards in SSMS to migrate everything
There is no "downgrade" possible using backup/restore or detach/attach. Therefore what you have to do is:
Backup the database from the server running the new SSMS/SQL version.
Import data from the generated .bak file, by expanding the "Tasks" menu(after right-clicking the target database) and selecting the "Import Data" option.
You can generate script from Task menu

How to migrate a SQL Server database to a lower version
A client has no option but to migrate from sql server 2000 to 2008 within the next few days. Tests have shown unacceptable performance degradation in vital functionality in 2005 but not in 2008. Good stuff however, the application uses DTS to import external market data into the database and DTS is no longer supported by 2008.
Until such time as the function can be rewritten, I'm thinking the import could be done in an instance of 2005 and the data (from one table) subsequently uploaded into 2008.
(a) is there an alternative option?
(b) if not, is there a simple way of achieving the data upload from 2005 to 2008?
Any assistance/advice gratefully received.
I might be misunderstanding what you need to do, but one thing you can do to move a database from from 2005 to 2008 is to just back up the database on the 2005 instance to a .bak file: right-click on the database in the Object Explorer in Management Studio (or whatever it's called in your version of SQL Server!), and do Tasks -> Backup database, and save it somewhere you can see from both instances. Then go to the 2008 instance do "Tasks -> Restore database" in the 2008 instance and the restored copy of the database should just work in 2008.
I think you might have trouble going the other way though, with this method.
You could use an SSIS package to execute the DTS packge, and AFAIK you can execute DTS 32 bit in SQL 2008 (MS link). The other option would be to run the database in a compatibility mode which ~may~ avoid the performance issues you're seeing. All in all, you might be better off rewriting your DTS with SSIS. The concepts similar and you shouldn't have too much trouble recreating it with SSIS.
