Best utility to migrate data to diff dbspaces?

We're migrating a database from one machine to another. We have to move some tables to *different dbspaces of differing sizes*. At first dbexport looked like the best utility to use, since it gives a high degree of freedom in placing tables. However, it doesn't seem to run if other users are accessing the DB. We wanted to set all tables on the original server to Select-only access for the duration of the data migration to diminish the impact on users - DB at least still up and accessible. But this idea won't fly if we can't run dbexport while users on on. (I don't recall seeing in the manual that it had to have exclusive access!). Any alternate suggestions or strategies? -- * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ADDRESS ALTERED TO FOIL SPAMMERS: Remove "*NO-SPAM*" to reply.
