Do the code versions on all controllers have to be the same for Centralized Licensing to work%3F

My Central license server (NBP-WLC-Aruba-01)  is running 6.4.3.7 and I recently upgraded 2 controllers (NBP-WLC-Aruba-03 and -04) to  Version 6.5.0.2 and since that time they are not picking up thier licenses from the Central Licensing server/controller.

On the Licensing server I see log such as these but i have not been able to find out any information on these yet:.

I'm thinking it is the code version but I'm getting ready to upgrade my code WLCs as well and want to make sure I don't break the licensing on my core controllers.

Re: Do the code versions on all controllers have to be the same for Centralized Licensing to work%3F

 update....

 

I bit the bullet and did the code upgrade on my 2 Master controllers and it does appear that the code version have to match, or at least there was something that changed from 6.4 to 6.5.

 

When I upgrade one of the core controllers it too lost access to the Central License controller.  I then upgraded the License server and all the other Master controllers were able to communicate again and all the controllers now have access to the Shared licenses again.

Re: Do the code versions on all controllers have to be the same for Centralized Licensing to work%3F

old topic, but for reference the 6.5 documentation says something about multi version, 6.4 didn't so it might have indeed changed

Multi-Version Licensing
ArubaOS supports multi-version licensing, which allows centralized licensing clients to run a different version of ArubaOS than the primary and backup licensing servers. If a license is introduced in a newer version of ArubaOS, the primary and backup licensing servers set can still distribute licenses to licensing clients running an older version of ArubaOS, even if the licensing client does not recognize the newer license type.
This feature is only supported in deployment topologies where all are configured as master controllers. Both the licensing server(s) and licensing clients must be running a version of that supports this feature. The multi-version licensing feature is not supported in a topology where a single licensing server or a pair of primary and backup licensing servers are connected to one or more local controllers.

Thanks do36874, for this info. 

 

I ran into the same issue and after running licensemgr debug, it was obvious you had already hit this problem and did the dirty work :-D

 

Just wanted to say thanks for providing the info to the community!!
