Migrate SQL Server database 2012 to 2014 - sql-server

I have database that runs on SQL Server 2012. Now I need to move this database to new PC and run it on SQL Server 2014.
What is the best way to do it? I far as I understood it is not possible to backup in 2012 and restore to SQL Server 2014.

Yes, you can restore a SQL Server 2012 backup into a SQL Server 2014 instance. See here.
Please note, you cannot go the other way - you cannot restore a SQL Server 2014 backup into a SQL Server 2012 instance. See here.

Is SQL Server 2005 database compatible with 2008?

I don't know if the title is correct but well what I'd like to ask: is it possible to import my database from SQL Server 2005 to 2008 or is the database in SQL Server 2005 compatible with 2008? I'm still a newbie.
Thanks
You can restore an SQL Server 2005 database on SQL Server 2008.
You can not restore an SQL Server 2008 database on SQL Server 2005.
Generally speaking, at the time of writing,
you can restore any database starting from SQL Server 2005 on a newer version of SQL Server (up to 2016), and
you can not restore any database on an earlier version.
You might want to increase the compatibility level of your DB after restoring it on a newer SQL Server version.
Yes. They are compatible. You can use a backup to transfer all the data.

SQL Server express backup

Can I use a SQL Server Express database backup file to restore that database on a full fledged version of SQL Server. I am particularly looking at SQL Server 2008 Express to SQL Server 2012 Enterprise. And if so how?
Lets be clear about one thing first, SQL Server Express , Standard and Enterprise are the Editions.
SQL Server 2005 , 2008, 2008 R2 and 2012 are SQL Server versions.
Now coming to your question whether you can restore a database from 2008 Express to 2012 Enterprise?
The Simple Answer would be YES you can.
A couple of things to keep in mind.
SQL Server Editions has no limitation you can backup and restore databases from one Edition to another without any restrictions (Except SQL Server Express which can only accommodate databases upto 10 GB). Other than this size limitation in SQL Server express, all is good.
Whereas SQL Server Versions has a very strict limitation, You can go up 3 versions but cannot go down at all.
For example if you had taken a backup on SQL Server 2008 (regardless of Edition) you can restore this backup onto a SQL Server 2008, 2008 R2 , 2012 and I think also on 2014. But you cannot restore this onto a SQL Server 2005.
I hope the explanation clears some confusions.

SQL Server 2014: Restore old backup

Tasks -> Restore -> Database
Select device option -> Pick up the .bak file
At the options select Overwrite
ok
Thanks in advance.
You are trying to restore a SQL Server 2000 database on SQL Server 2014. This is not supported.
You will need to restore your database on an instance of SQL Server 2005, 2008 or 2008 R2 first, then back it up from there, then restore the new backup on SQL Server 2014. Microsoft explains this here how to on SQL Server 2012.
I don't think you'll be able to jump that many versions from a SQL 2000 backup straight to 2014. It's just too much of a jump with too many changes to be made.
Restore it to SQL 2008 first, then back this up and then restore to 2014.
Here's some links to guides that should be able to help you;

First of all not, that you can restore your SQL Server database backups on a different version of SQL Server, but with one tiny restriction. You can restore your backups only upwards, it means that you can restore from SQL Serve 2005 to 2008 or from 2012 to 2014.
But it has to be admitted, there is no way of restoring your database backups from SQL Server 2012 to 2008. SQL Server has such restriction because every new version has modifications in the binary of the database and their storage.
Also, you can't jump forward two versions, for example, you cannot restore a database backups from SQL Server 2000 to SQL Server version 2014 as you are trying.
As it has recommended above you need to restore in few steps. Firstly restore it on SQL Server 2005 or 2008. make a full backup and then restore it on SQL Server 2014.

Can we restore SQL Server 2008R2 backup on SQL Server 2014?

Currently, one of our product running on the SQL Server 2008R2.
For new installation client want to go for SQL Serer 2014 because at this location Microsoft is not selling licence for the SQL Server 2008R2.
In SQL Server 2014, you can restore a user database from a database backup that was created by using SQL Server 2005 or a later version. However, backups of master, model and msdb that were created by using SQL Server 2005 through SQL Server 2012 cannot be restored by SQL Server 2014. Also, backups created in SQL Server 2014 cannot be restored by any earlier version of SQL Server.

Yes.
Wen you restore database backup that created with older version of SQL Server in to new version, SQL Server automatically updated your database in new version. But don't change compatibility level of your database. You can change Compatibility level of your database after restore complete by following query :
ALTER DATABASE test SET COMPATIBILITY_LEVEL = 120
In SQL Server 2014 SP1 there are breaking changes to the restoreheader definition (3 new fields added).
If you use it, you should have a look at this thread:
breaking changes to SQL Server 2014 SP1 - restoreheader

Convert /Attach SQL Server 2005 .mdf to 2008 .mdf?

I have SQL Server 2005 .mdf file and now I need to attached the same to SQL Server 2008
so how can I do the same.
Is any such tool is available , which convert 2005 .mdf file to 2008 .mdf file ?
As I do not have access to SQL Server 2005 at all .
Best practice is to backup the database using SQL Server Management Studio with SQL Server 2005, and then restore it on SQL Server 2008.
But you can simply attach the SQL Server 2005 .MDF file to SQL Server 2008. SQL Server will convert it for you - it is able to read data files from older versions of SQL Server.
I would suggest attaching to SQL Server 2008, performing an SQL Server backup, then restoring it back to SQL Server 2008. This will cause the database to be recreated, and will alert you to any data issues.
Cheers,
Peter
When you restore database backup(2005) to SQL Server 2008 , SQL Server restore your backup and update it's to new version. But SQL Server don't change compatible level of your database. you can change compatible level of your database by following query.
ALTER DATABASE test SET COMPATIBILITY_LEVEL=100;
