Continue using TSE source server after migrating clients licences

Hello,

Soon, we'll have to transfer our 30 licences TSE from a windows 2003 Entreprise to a 2008 R2 RDS, after this migration, we'll have 2 months to train our users with this new install, during this delay, we'll have to keep using our "old" TSE server in production.

So we'll have to use both TSE/RDS servers in same time.

Is it possible to use the old windows 2003 ts server (clients +20) even if its licences are migrated ?

Thanks, regards,

Clémence
