  • Are you using the EMS to initiate the moves? If so, use the -MaxThreads parameter to increase the number of concurrent moves.

    However, the default is "4". If only two are moving at a time there's probably some throttling going on because of poor performance. Increasing the concurrency probably would result in worse performance.

    I forget if the restriction on the 2003 side is "2". If it is, you can run multiple sessions and increase the concurrency in that way. It's not the same as increasing the number of threads, but multiple processes may get you the increase you need. Just don't overdo it. :-)
