Need to upgrade two CakePHP sites from v2 to latest version

Hello, I'm looking for an experienced CakePHP developer to help upgrade two of my existing CakePHP websites from version 2 to the latest version. I haven't been doing a lot of periodic upgrades, so these sites need some work to be brought up to the current version. Fortunately, I do have existing backups of both sites that can be utilized. Anyone who can help complete this project is greatly appreciated. Thanks!

Your bid is the project budget.
