oh, the procedure to get a license and let run the same LMS application on another server at the same time as the first one is running, is very simple:
just buy another license ! ;-)
the license doesn't care about the platform but about the number of installations
When you 've got one license for LMS 2.6, it can be used for 1 instance of each application in LMS 2.6 - except of Common Services (former CDone)-which does not need to be licensed.
So every additional installation of the same application needs a new license .. (2 RME installations = 2 LMS licenses)
