upgrade cakephp from 2.3 to 2.5 - cakephp

I have a problem with some code and I found out that I have an older version of cakephp installed on the server I am using which is ver 2.3. I want to upgrade this version from 2.3 to cakephp ver 2.5 .I need to:
1) place new version in the lib/cake folder (overwrite?)
2) check migration guide for any function differences.
The advice given here was to simply refer to the migration guide but this guide says nothing about installing and mentions only upgrading from 2.4 which I don't even have?
I don't want a potential headache moving from 2.3 to 2.5.

Upgrading CakePHP from 2.8.0 to 2.10.20

Currently, I have a live project in CakePHP 2.8.0 where PHP Version is 5.6.40.
I need to upgrade my CakePHP to the latest version. Can you suggest any new version that I should upgrade to without having many changes? Should I upgrade to 2.10.20 which is the 2019 release? Also, I don't want to change the PHP version which is 5.6.40 now.
Upgrades to CakePHP need to be done iteratively, ie. you'd need to cover everthing in the 2.9 migration guide before going through the 2.10 migration guide.
I'd suggest taking a copy of your code and installing the most recent version of CakePHP 2.10 for it and going through the CakePHP 2.9 Migration guide and then the CakePHP 2.10 Migration guide
Both 2.9 and 2.10 are compatible with PHP 5.6
After doing this, you can consider upgrading to CakePHP 3 which is a much bigger upgrade

Why is framework version 7.3 not available for download on the Sencha Support Site?

Last week, I downloaded Sencha Architect version 4.2.9. It installed Sencha Cmd version 7.3 and version 7.3 of the ExtJS framework as a part of the installation process. However, 7.3 is not available as a separate download on the Support site as it would typically be. Why is that?
Current download is only 7.2.0.66 - If you got 7.3 I'd say that was an accidental leak of 7.3 if you got it...
I'm only getting
both support portal and npm are only supplying 7.2 series
Would love a copy of 4.2.9 if you have one... I can't seem to get that either.
Ext JS 73 is now available on support portal.

Upgrading cakephp 2.x to 3.x

I'm trying to upgrade several of our cakephp 2 apps to cakephp 3 using the upgrade tool but I'm a little lost. On this blog, in one of the comments it says that my application will need a copy of cakephp 3 for the upgrade. Do I install it in the root directory of my app or where exactly?
Should the commands be run like this
bin/cake upgrade all /root_directory/
or
bin/cake upgrade all /root_directory/app/
Any help is appreciated.

the codenameon demos under netbean 3.2 do not work

IDE: NetBeans 8.2
Windows 7
I installed codenameone under NB 8.2 and can't get a demo to load. They all say 'The project source/binary format is older than minimal supported one (1.6).'
Also can't get the codenameone plugin to update.
any suggestions? thanks.
There was a problem with older plugins which should work for 3.5.6 or newer.
As a workaround make sure the project is set to use Java 8 and open the build.xml file. Replace all references to 1.5 to 1.8.
This resolved my "Resolve Project Problems", but I still get this error when running the ToDoApp (and others) :
/Users/nnnnn/netbeans-tutorial/All-codenameone-demos/ToDoApp/build.xml:51: taskdef class com.codename1.build.client.CodeNameOneBuildTask cannot be found
using the classloader AntClassLoader[]
none of these hints helped me: https://www.adam-bien.com/roller/abien/entry/how_to_fix_the_libs
MacOs 10.14.6, Netbeans 12.2,
Now I came a little longer as I in preferences, Java added, Add JAR/ZIP:
.codenameone/CodeNameOneBuildClient.jar

There was an issue communication with the cmd server.Check to make sure you have the latest version of cmd installed

I have upgrade a solution which was developed in Exts JS 4 with sencha architect 3 to Exts JS 5 using sencha architech 3.1.After upgrading ,i am getting following error.
"There was an issue communication with the cmd server.Check to make sure you have the latest version of cmd installed."
Could someone help me????
I had this issue and I resolved it by running the sencha CMD server.
I was able to start it up using the instructions from: http://www.ladysign-apps.com/developer/use-the-sencha-cmd-webserver/#.VHGF5dKUdAo.
I imagine there is more info on this in the Sencha documentation but this seemed to make the error go away for me.
I had to download and install the Java JDK form Oracle.
Java SE Development Kit 8
Mine is running on a Mac OS X Yosemite.
And i was using Sencha Architect 3.2
