I would suggest that the best way to deal with changing radically the
underlying OS is to make a replica on a new machine and then get rid of
the old one if possible.

If multiple replicas are already available I would just wipe out the
machine, re-install, then replicate again.

Just pay attention to backup things that may be only on the first master
(for example the CA if you used selfsign).

Simo.
