Upgrading CakePHP from 2.8.0 to 2.10.20

Question

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.

Answer 1

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
