Hello,
I am migrating a forest/domain from Windows 2003 AD to Windows 2012R2 AD, by adding new domain controllers, then demoting the old DCs and raising the forest/domain functionality level to 2012R2.
In the domain I have a 2-node MSSQL 2008 cluster, running on Windows 2008 Ent. servers (and DoubleTake for storage replication). We are keeping these domain member servers and the MSSQL cluster as they are, the same version of Windows and MSSQL.
Should I change anything, should I expect any surprise related to the migration to new domain controllers and new domain functionality level?
Since I am not moving/migrating the 2008 MSSQL cluster to 2012R2 servers, I believe I should not have any impact.
Thank you for your advice.
