We have a number of workstations with version 17.2 that work on a floating license server
We want to know if it can be upgraded to version 17.4
If so, should the floating license server be upgraded as well?
In addition, how can you know where the license was purchased from?
Cadence licenses can be either time-based licenses or perpetual(forever) licenses. Forever licenses tend to not get updated as they don't expire.
Opening LMADMIN and running a license status query should have a Version field that would have the scope of the licenses (17.2 or 17.4 in your case.)
Or, if you can access it, the license text itself on the license server would call out the version scope that the encryption key is made for..
Just don't post your entire license file. Ick...
