If I upgrade ISPConfig do I will lose the master-master replication?

[voltron81]

Hello,
I've a master master replication email server, using a replication of /var/vmail with glusterfs and a master master replication of some tables of dbispconfig (the one releated with the email and a bit more).

Now this is the question: if I want to upgrade ISPConfig from 3.0.1.4 to 3.0.1.5, running the upgrade script do I will lose this replication?
With the upgrade, do the dbispconfig rewrite something?
Thanks
Michele

I've never done a upgrade on such a setup, so I dont know.

The ispconfig installer dumps the database, emptys all tables installs new database tables and loads the database data again, so it might cause problems. But I really dont know how mysql handles these changes.

yes if is dumbing the database and replace it with the new one I will have problems... for the moment is better if I don't upgrade...
Anyway when I'll upgrade, I've just to repeate the mysql master-master replication...

Thanks
