Ok valid concern lol .... if you have backups you should still be ok. I'm not positive on if there are any serious schema changes etc but as long as your replication isn't one to one (named ou's and domains etc) then the replication should still be ok. Another plus is that ZCS is very much self contained so even if you are running accompanying applications (like Samba etc), I dont think there's a huge risk in upgrading your actual ZCS install.
This might be a good test to verify your config that's for sure ... although it's nice in these situations to have a mirrored test environment. If you can verify both your primary and replicated LDAP stores as well as your controller config through Samba ... I would think you could walk this pretty easy (with a little down time).
Dissable users from connecting (scheduled down time), backup your Samba config and winbind if applicable, force replications of your LDAP stores, shutdown NON ZCS services on your slave and master, upgrade ZCS, bring up slave and start Samba services again.
Obviously you know your environment better than anyone here but so this is all speculation but if you have a decent backup of your existing running config you should safely be able to do the upgrade.
Blah blah blah this is my own personal opinion and it is in NO way endorsed by Zimbra or its' affiliates
