i think its possible but i would like to know if you got this scenario
HQ
Master and Backup Master
Remote Site
2 local controllers for local redundancy
Remote site 2
2 local controllers for local redundancy
all the controllers will be local of the master on the HQ
The question is that if you can use the same set license and just install it on the master on the HQ and share it to all the controllers, incluiding the remote site local controllers and remote site2 local controllers
Cheers
