I have 2.1.0 Expression Engine and planning to upgrade to 2.5.2.
I realized that I renamed the “system” folder to “ee” at first time I installed 2.1.0 EE. Now coming upon upgrade, I don’t know if I should change my “ee” folder back to “system”. I found two places to change “ee” to “system” which would be “index.php” file and Admin > General Configuration > URL to your Control Panel index page.
Are there any other places I should find to change “ee” to “system” before I upgrade?
Or better yet to add changes to certain files in the upgrade package to keep “ee”?
