Hello OpenProject Forum

I have a question about upgrading to OpenProject V16. Do I have to migrate the PostgreSQL database ti V17 before or after the upgrade?
The migration description refers to PostgreSQL version V13.
https://www.openproject.org/docs/installation-and-operations/misc/migration-to-postgresql17/

What is the difference if I have version 14.18?

On the ubuntu i have installed the Postresql version 14 and 15

Many thanx.

Hello, has anyone had a look at the case? Is there a way to switch to autoinstall?

Finally, it works, but I get an i386 architecture error. Is this critical, and if so, how can I solve it?
