What licensing do you have for VMware vSphere?

Are these two standalone ESXi servers, with a SAN and vCenter Server ?

do you have a SAN ?

You could use a Migration, vMotion if you are licensed, or Share Nothing Migration?

if neither of the above, do the following power off one DC only, and then Export and Import.

Do not use VMware Converter, whilst the VMs are Live and Powered On!

Hi,

yes Esxi are on SAN and we have Vcenter Server also

 if we Used Vmotion for migration what precautions should we take before migration and how.

                              or

Can we export and import Domain Controller without any issues. i have heard that Export and import to OVF/OVA template, will face issues after restore as it is DC server. i am not sure.

thanking in advance

If you have a SAN, and vCenter Server, and you have a license for vMotion, there are no precautions, just right click and Migrate.

vMotion is designed, very stable to migrate live VMs.

Make sure that networking on both hosts is setup identically.....but there are pre verification checks performed by vCenter Server before you vMotion, call them pre-flight checks, or pre vMotion checks.
