I have prepared 6 servers for exchange 2013 installation :
2 for DC and ADC -- OS windows server 2012 R2
2 for CAS Role -- OS Windows server 2012
2 for Mailbox Role -- OS Windows Server 2012
As Windows Server 2012 R2 is not supported for installing Exchange 2013 i decommissioned 4 Servers ( CAS and Mailbox ) and starting from scratch.
Will the above scenario work now ... like having Domain controller OS in Server 2012 R2 and CAS and Mailbox Server Roles in Server 2012 Version ?
How to install individual Server role for exchange server 2013 ( i mean CAS role on 2 servers and Mailbox on 2 servers). are there any steps to follow on for this ?
Please let me know on this.
