Above is my current Exchange environment. We just found out that we need to convert some Enterprise editions to Standard editions. Enterprise keys were used in situations where they should not have been. Our plan is to replace the following servers: CAS07A,  CAS07B, EDGE07B & HUB07C. The new servers would be Windows Server 2008 R2 Standard SP1 running in VMware ESXi 4.1.

My question is this: Is this configuration supported by Microsft and is it even feasbile WITHOUT reloading other servers with the same roles. For instance... can I have Hub transports with different operating systems? Is there any reason why the edges would have been setup with Enterprise licenses? As far as I can tell I just need my 3 2007 mailbox servers to have Enterprise licesnes (ignore the 2010 stuff - this is just in testing right now).

Keep in mind that I already am aware that my 2007 Exchange servers running on VM's with Windows Server 2003 are not supported configuration. I inherited the situation - I didn't create it.

    OK, here are the answers:
    - You can run Exchange 2007 SP3 on Windows Server 2008 R2.
    - It is supported (same article).
    - You can have different OS for different roles.
    - You must have same versions of Exchange HT and CAS for relevant MBX. So, if you have both E2010 and E2007 MBX servers in a single site, you must also have both E2010 HT and CAS and E2007 HT and CAS servers.
    - Enterprise is not required for Edge servers - only for Mailbox servers to increase the number of databases.
    - E2007 on W2003 on VMware is outside of MS jurisdiction, so if the virtualisation vendor supports it - you're OK and MS won't object, though they may ask that you replicate the problem on physical platforms.

    Good luck.

    Thanks Nenadic! That is exactly the answer I was looking for.

    I have already reloaded one of my CAS servers on Server 2008 R2 and it is running great.
