Well most of the people are now back up and running with email, all of the old MAPI users are using the ZM Connector and a few of the OSX people are using the iSync connector (nice that people can finally see each other's diaries)
I've got the last 30 or so accounts to migrate over the weekend and then the CMGPro server will be pensioned off.
I've also got 12Gb of RAM to slap into the Zimbra server.
Initial feedback from users
- The webmail is better
- The ZM Connector is better (and more reliable) than the CMGPro one.
- You can see mac users diaries?!
- Where has my email gone? (those who haven't fully migrated)
For those looking to undertake a move from CMGPro, I'd suggest that the move is worth it, but isn't simple, this is something that needs to be addressed. Creating the accounts was easy (using my perl kludge) the groupware migration and the data migration has just been a complete slog.
People are only now trimming their accounts as we're imposing quota limits shortly...
The largest email account is 19Gb, and having 100+ people rock up on Tuesday and connect to the mail server absolutely creamed it as all of their clients tried to sync up..... so if you migrate a lot of users / lot of data, try and do a staged switch on of mail clients.
New SSL cert is place now, and I've also gone through the
performance tweaking stuff in the wiki and applied all of that with the exception of the LDAP tweaks.
Final thoughts?
- Have plenty of coffee on standby for change over day.
- Ensure you have a server to migrate to, you can't do this all one server (as we originally tried)
- Users will ignore all your email and phone on their first day on the new system saying "where's my email"
Still mostly done now, just a bit of mopping up to do and getting the remaining 200 people using connectors rather than IMAP.
The fun never stops.
