Seafile Server Upgrade - older versions displayed only

Dear Seafile users,
I’m using Seafile Server on Debian and want to upgrade from V8 to V9, but all I see are the older versions in the “upgrade” folder. How do I get the freshest list?

For the upgrade, you need to go in the Seafile folder for v9. In your case /opt/seafile/seafile-pro-server-9.0.x/ (with x being the downloaded maintenance version).

Thanks for your reply!

This is what I see:

Does it mean I have to first download .tar file of version 9, extract it here in the seafile folder and then proceed? Can’t imagine how it could work though.

please see: Upgrade manual

Ok, this was what I was looking for: Upgrade notes for 9.0.x - Seafile Admin Manual

Thanks for help from @rdb and @germeier!
