That's what I thought, thus not making sure I had backup files before
upgrading os. But I now have a couple of FDB files that I can't connect
to. I get "XXX is not a valid database". I had a backup file of one of
them and restored it, which works, but I would like to gain access to
others, where no backup file exists.

The files are from 2006-2009 and probably created with Firebird 2.0, but
that shouldn't matter, should it?

That's not an issue.

That might be worth a try.
