How many agents can Domain Migration Administrator send out at one time? (NETIQKB19543)

goal
How many agents can Domain Migration Administrator send out at one time?

fact
Domain Migration Administrator 7.x

fix

Domain Migration Administrator runs a thread pool of 20 agents to enable the processing of multiple computers at the same time.  This means that Domain Migration Administrator (DMA) can send out no more than 20 agents at a time.  As one or all of these agents land, another thread is dispatched.  So, although DMA only sends out a maximum of 20 agents simultaneously, there could be more agents actually running at any one time.

Please note that this information can also be obtained from Appendix C of the Domain Migration Administrator and Server Consolidator User Guide.
