huuh????, I know some of us have huge TSM database, but export/import for all node data for such a server is highly unlikely to complete in our lifetime. I'd say, either go for the downtime, or just build a new server (maybe export server) and then just point your clients to the new server. You need bigger faster hardware anyway for TSM 6..... > Let the list know how you got on! -- Met vriendelijke groeten/Kind regards, Remco Post
