Exchange 2010 to 2013 different domains

I have a customer who wants to migration from Small Business Server 2011 with Exchange 2010 to a completely new domain with Server 2012 on Exchange 2013.

Guides?  Gotch-ya's?  etc?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Thanks tqfdotus but those articles do not show any information about Exchange and cross domain migration coming from SBS to Server 2012 Standard.

Sorry, guess I was going for the 'etc.' category instead. Let's try a little harder...

This guide is for migrating from SBS2011 to Server 2012 Essentials:

This article adds a little flavor to it:

Here is a guide to updating domain controllers to Server 2012:

From what I can find, the migration to Server 2012 Essentials is, for lack of a better word, essentially the same as migrating to Server 2012 Standard. Except the Server 2012 Standard does not seem to have a "migration mode" so there are some additional steps. See

The one point of clarification that no one has really ask is, do they want a completely new internal domain name from what the SBS server is using, or do they simply want to change the external domain for email, remote access, etc.  It's also not clear how many users they have, and why they are leaving SBS 2011.

If they want a completely new domain internally, it's just a clean install of server 2012, recreation of users accounts, security groups, etc.  you'll have to copy all data to an external drive then back to new server.  Email will have to be exported to.pst files and then imported into the new Exchange server.  All this because SBS does not permit establishing trusts with other domains.

I've decided to set up Exchange 2010 on the new domain and do a lateral move then upgrade to 2013.  What I've read seems to point more towards that type of migration.

Agreed. Best of luck! Let us know if you have any problems.

As I indicated before...if you're setting up a completely NEW Active Directory Domain, you can't migrate, not matter what version of Exchange you're doing because you CAN'T create trusts between an SBS domain and another Active Directory domain.
