Dump and Restore
1. Backup the databases on the device, drop the databases, drop the devices.
2. Rebuild the new devices.
3. Rebuild the databases (Make sure you recreate the fragments correctly - See Ed Barlow's scripts (http://www.tiac.net/users/sqltech/) for an sp that helps you do this if you've lost your notes. Failure to do this will possibly lead to data on log segments and log on data segments).
4. Reload the database dumps!
Twiddle the Data Dictionary - for brave experts only.
1. Shut down the server.
2. Do a physical dump (using dd(1), or such utility) of the device to be moved.
