A customer is using a very old version 3.9.9 of AdRotate Pro. He already bought a new license to get updates to the latest version.
Before we update, is there anything special we should take care of updating from such an old version to the latest version? I’ll update the plugin via FTP. Is there some kind of migration necessary, because of the old version? Is it recommended to update in smaller steps (3.9.9 -> 4.x -> 5.x)?
Any version older than 4.0 is no longer supported for updates.
So updating to version 3.22 -> 4.0 -> 4.18 -> 5.0 and then 5.7 is usually the way to go.
You can use AdRotate Banner Manager for that or get the update service where I do it for you.
