Multi version install

How're y'all doing today?

Here's how it is. I have two Zimbra 4.5 servers OE running, the main server replicates to the backup every night at 12 am. I want to test Zimbra 5 on the backup server before I go live.
Is it possible to replicate from Zimbra 4.5 to Zimbra 5?

Please, urgent response would be appreciated

Unfortunately not. You would be better setting up a separate server/VM for testing ZCS 5. This is due to schema changes etc when upgrading from 4.5 too 5.

That's painful.
Anyway, if I upgrade both the production and backup servers, will it modfy any of my replication settings?

[uxbod]

How are you performing the replication ?

[yusufu]

I'm running a test environment and I need to install and re-install Zimbra 4.5 and Zimbra 5 serveral times.
How do I unistall Zimbra
