Unraid - Seafile CE to PRO Container Migration/Upgrade

Hey guys!
I will keep it short, I started hosting a Seafile docker on my Unraid server. Now I wanna migrat/upgrade tp the pro version so that I can use onlyoffice in the browser. For rev. proxy I us nginx in a sep. docker.
I tryed following the official guid on how to migrat from CE to PRO.
I also tryed a lot of diffrent stuff like replacing the main image with the provided seafile pro image of Seafile from Harbor.

If anyone has any expirience with unraid and Seafile I would be very happy if u could help me.
