It doesn't matter, updater will stop/start services as needed

You have to rollback all snapshots for the whole topology and then you 
can start IPA, otherwise replication conflicts may happen.
So I suggest to have snapshots of all servers before upgrade.

This is the best for integrity, but in case there is no/low activity on 
servers, then one by one snapshots may work too.
