During CommCell Migration, you can migrate the virtualization client, Virtual Server Agent (VSA) proxy clients, or both. After you migrate VSA proxies, you must reset the proxy references for the instance and any subclients that refer to the proxies. For Virtual Machines that are backed up with indexing V2, you can migrate individual machines.
Note
After the CommCell migration, you cannot perform a file-level browse operation on a Indexing V1 virtualization client.
