I’m looking to add an Exchange DR site to our existing Exchange 2010 configuration.
Our current system is as follows.
All servers are 2008R2 datercenter for the O/S (with all win updates installed)
2 * DC,DNS
1 * Exchange 2010 sp3 CAS + HT (not setup in CAS ARRAY)
1 * Exchange 2010 sp3 MBX (setup with 4 mailbox + 1 public folder stores)
(this is datacenter on VMWARE 5)
I have looked at the various ACTIVE/PASSIVE ACTIVE/ACTIVE…etc… options and am happy with these…..
BUT my question is……. If I implement a DR for exchange 2010, can I install the exchange servers onto server 2012R2 or does my DR site need to have the same operating system as the main site?
