I have 3 ESXI HOST servers.
I also have two domain controller. DC1 = virtual = windows 2008R2 > ESXI HOST SERVER 1 ADC = virtual = windows 2008R2 > ESXI HOST SERVER 2
Can I use VEEAM QUICK MIGRATION option to MOVE DC1 to new ESXI HOST SERVER 3 ?? without damaging anything ?
what are the best options available? (taking DC offline/shutdown is no issue as it would be done in night when there is no load)
Yes, you can use Quick Migration in this case, however I would also recommend leveraging replication jobs with AAIP enabled to move your VMs to another host.
This might sound crazy, but if you can shut down the VM DC1 you can move the VM with vSphere Web Client: right click the VM and choose Migrate...
This leaves the moref ID for backups unchanged.
If the esxi hosts are not managed by a vCenter server, you can just unregister the VM on one host and re-register on the destination host if your storage is shared.
Moving a powered off VM is much easier than a running one if you cannot leverage vMotion.
I am looking to find out if I can Quick Migrate 2 Active Directory Servers (2012/R2) to a new VmWare host. Unforutnately vMotion is not an option as I have the Essentials License. Both hypervisors are 5.1 based. Is there any known issues with doing this? Would it cause an AD rollback state?
As mentioned above, the best option you have is to use replication job with Application Aware Image Processing option enabled. Otherwise (Quick Migration), be aware to power DC VMs down first in order avoid application consistency issues.
