 Moving from single to multi server
We've been running single server Zimbra for some time and need to move to a multi server installation to scale.
Having read through the multi-server installation guide and various forum threads, I can see methods for full migration from one setup to another, but not a lot of detail on extending an existing single server setup.
Unfortunately, and short-sightedly, we called our one server zimbra.domain.com, and didn't CNAME it for IMAP/HTTP(S). At the moment, I'm looking at using the proxy functionality in 5.0 to transparently redirect users over time as we migrate them to a second/third/nth mailbox server we'd setup.
Before I go making larger plans and testing things too deeply, has anyone done this before and if so, do you have any recommendations or warnings of pitfalls?
Thank you,
