No - You cannot have v8.6 media server running a v10 RAWS,
I've never tried it, but this might work, depending on what registry values are set.
shut down all BackupExec Services, and do a local install of the RAWS
Then you'll need a couple of CMD files, one to stop the RAWS and start v8.6 and the other to stop v8,6 and start the RAWS
Used to do something similar when migrating from v6.11 to v7Message was edited by:
