Migrating users from 3 separate sites, one of which has a slow WAN link. Less than 200 users total. Can I build 3 migration consoles using the same MMAD license, one for each site?

Migrating users from 3 separate sites, one of which has a slow WAN link.  Two different source domains, less than 200 users total.  Can I build 3 migration consoles using the same MMAD license, one console for each site or do I need 3 separate licenses?
