Until now we have had Veeam B&R and VCenter Server running on a win2008r2 VM (very satisfied with veeam

However I wanted to start using the VCenter Server appliance, I just installed and configured it and now I have two questions:
Should we just install veeam B&R on one of our domain controllers, or what is 'best practice' in this scenario. I assume you cannot install veeam directly on top of our vcenter appliance

What is the preferred way to transfer the license, the config is simple so we'll just do that from scratch but I don't want to jeopardize my license

Thanks for comments
