Attachements and trimmed backups

Attachements and trimmed backups

Tonight we are transitioning to a new server for Servicedesk.  To save time, I was wondering if I can perform a trimmed backup and restore, then manually copy the attachments directory to the new server after the restore is done?   What happens with Archived requests?

Also, how does Alias work?  If I have the old server named Helpdesk and the new server called support desk, do I just add the name of the old server to redirect clients?  What happens if the old physical server is still running, but the ServiceDesk services are stopped?

Thanks,
Dave
