Re-building a database server

I have a client with a database server (v7.24) which contains a single database, but which has multiple dbspaces. It's important that a table remains in its allocated dbspace because the application (Lawson) maintains its own table/dbspace mapping. I want to re-build the database server because it currently has stupid chunk names, and I want to impose a new standard. Obviously I must dbexport or ununload, then scrap and re-build the server, then dbimport/onload. I'll have no problems restoring tables to their allocated dbspaces with dbimport. But it will be slow (this is a 10GNyte database). But onload will only restore all tables to the dbspace specifed in my onload statement. Does anyone have any other ideas? Thanks Neil Truby aracnet Limited Weybridge, UK P.S. Furthermore, I may want to repeat this exercise on another client's v5.02 server, and put mirroring on the re-built server. Does anyone have any views on whether it's quicker to re-build the server first with dbimport/tbload, THEN put on mirroring, or vice-versa?
