Hello,
Currently we are trying to setup a new DR site with SRM that is not a flat network with our main site. The setup is as follows
10.70.10.x /24 Main site
Active Directory Server/DNS (AD01)
Active Directory Server/DNS (AD02)
vCenter Server (VC01)
SRM Server
Exchange Server (EXCH01)
All other VM's
10.70.20.x /24 DR site
Active Directory Server/DNS (AD02)
vCenter Server (VC02)
SRM Server
Space for recovered VM's
Setting up the replication and recovery plans is fine but I was wondering what the best practice was when changing the IP's and if there is any other ways around this like DNS masking or something. From the reading I have been doing it would appear the best way to have SRM set this up is do an IP address change during the failover and then have it run the DNSscript to change the DNS records on the active AD controller. My concern with this is the Exchange server as the rest of the servers won't have a problem with the IP address change/ DNS change and the AD01/AD02 will not be replicated. Also while reading up no the IP change / DNS change it would appear there is no way to actually run a Test Recovery Plan with DNS change as the changes are always made to the production DNS servers even though the rest of the VM's will be in the isolated network SRM creates for a test recovery plan.
So to recap my questions are
1.) Is there anyway to get around the IP change when your DR site is not on a flat network/same network
2.) How does Exchange handle the IP address change / DNS change
3.) Is there anything special that would have to go into the DNS script if we do change ip / dns for exchange or for testing
4.) Is this the most efficient way to accomplish this DR failover
Thanks
