Ferit

An abandoned tool on a NAS is a deadline someone else set for you.

Did this migration and the first step in the second comment is the one that saved me: writing down what each environment actually was, before touching anything.

Half of mine turned out to be one service that did not need a persistent environment at all, and rebuilding them as ordinary application containers was less work than migrating them properly.

Strongly agreeing on not migrating onto a platform release the week it lands. Doing both at once means any breakage has two candidate causes, and you will spend the evening deciding which rather than fixing it.
