Back Up Your Files Before You Migrate Them

If you back up and migrate files to the same server, you can assign a management class to files specifying that current backup versions of your files must exist on the migration server before the files migrate. The default management class includes this requirement. The HSM client checks for backup versions of files only on the server to which it migrates your files. If a current backup version of a file does not exist on that server, the file is not migrated.

If you back up files to one server and migrate them to a different server, the HSM client cannot verify that current backup versions of your files exist before it migrates them. Any management class that you assign to files must specify that current backup versions are not required prior to migration. Otherwise, you cannot migrate your files.
