Phased migration from Exchange 2007
« on: April 25, 2019, 03:35:37 pm »
I am trying to plan a migration from Exchange 2007 (AD Integrated to our internal corporate AD) to Zentyal as a standalone domain. Our internal domain is different than our registered live internet domain and Zentyal will be receiving mail under the external domain - duh. So there really is no need for it to be attached to the internal users. We have about 200 users but most of them are mail only users with no account on the internal domain.

It's a single server and single domain environment, so should be a piece of cake EXCEPT that I'd like to do a phased migration. I just need to ideas on how to pull that off. I can install it as a new mail server on a new address, but then the changeover would be all or none. How can I phase this? i.e. only have about 10-20 users trying it out and burning it in before going full live with it but still maintain my domain and email addresses exactly as they are (no sub domains etc).

Zentyal e-mail module depends on Samba module, so, in order to use it as mail server you have to migrate the domain directory control to Zentyal.

Samba4 is Windows Server 2008 compatible, so you could try to integrate Zentyal as additional domain controller ( if Exchange 2007 has this feature)  and, after the migration of service, you could assignt the FSMO roles to Zentyal.

This last process works but there is some issues ( see here https://forum.zentyal.org/index.php/topic,19978.msg110446.html#msg110446 )

Additionally, You can play with e-mail virtual domains in order to mantain the service up while the migration :)
