TS License Server Migration

Hi,

is it possible to have 2 activated MS TS Licenseserver (not AD integrated) for a short time of a TS Migration side-by-side with the same amount of TS Cals? So the users of the old TS (Citrix) Farm will be connected to the old TS Lic Server and new migrated Farms connect to the new TS Lic Server ?

Some time ago i had problems with migrating a TS Lic Server to a new Server when the clients wanted to renew the Device Cal and tried to connect to the old TS Lic Server. Theres a KB from MS out to delete a specific Registry Key then.

I want to avoid those Problems and having the Lic Servers Side-by-Side. Possible?

cheers,
Marcus
