In short, "ubik will do all magic for you".

The latest database version and the sync-site election are tracked
separately.  There have been occasional bugs in edge cases where
multiple servers go down in close succession that could cause the
"magic" to fail, but adding a new server while the old one remains
running should be just fine.
