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.....
