Migrate from Windows Server 2008 SP2 with Exchange 2007 to Server 2012R2 with Exchange 2013

Hi

We have a standard windows server 2008 SP2 server (Non R2) running Exchange 2007 SP2, we need to know if its possible to introduce a new DC running Server 2012R2 and also a separate Server running server 2012R2 and Exchange 2013, I can see a lot of talk about upgrading to 2013 exchange but not when you are running the NON R2 version of server 2008, please help.

You can, and the process is the same. Just dont try to introduce too much change at once (and that advice is not unique to your environment.) Do exchange. Or do your DC change. Then retire the old server for that service. Then do the other (exchange or DC) and then retire THAT old server. Slow and methodical. I've done several 2008 (non R2) to 2012 R2 migrations and there is nothing particularly unique compared to 2003 or 2008 R2 or even 2012 non-R2. Sake basic procedures regardless.

To answer your question above the answer is yes. Exchange 2007 SP2 is supported using 2012R2 DC's (see link below).

Exchange 2013, I can see a lot of talk about upgrading to 2013 exchange but not when you are running the NON R2 version of server 2008, please help.

In order to introduce Exchange 2013 you are going to need to upgrade your Exchange 2007 servers to Sp3 RU10 minimum.
See linke below for matrix.

OK so the fact I am not running Server 2008R2 doesn't matter at all?

Is there anything which should be done differently or in another order compared to the instructions I would see on something like petenetlive?

No it does not matter.

Is there anything which should be done differently or in another order compared to the instructions

Before you do anything you need to fulfill the dependancies first. So perform the steps in the below order...
- Upgrade all Ex2007 servers to SP3 RU16 (most recent, RU10 is minimum for Exchange 2013)
- Install/configure Exchange 2013 (requires a schema update)
- If you have installed Ru16 then you can continue, if you only installed RU10 then go to below step
- Completely migrate all Exchange 2007 to 2013
- Decommission Exchange 2007 servers

*note: if you try and introduce Server 2012 R2 as a domain controller and you still have Exchange 2007 in your environment then you will require to have a minimum of RU13 on all of your Exchange 2007 SP3 servers.

- Install RU13 minimum requirement for Exchange 2007 with 2012R2 Domain Controllers
- Transfer the FSMO roles to the 2012R2 DC's
- demote 2003 Domain Controllers
