Controllerless Networks

Dear All,
We have two Aruba 7210 Mobility Controllers (standalone mode). They are in Active/Standby HA. I want to upgrade them from 6.5.1.4 code to the 8.3. How can I perform this without affecting the users? 

Any upgrade document from Aruba for the above scenario is highly appreciated. 


Thank You

Are you going to be using a Mobility Conductor (virtual or physical) to manage your controllers?

If so:
Stand up your Mobility Conductor, and migrate all of your configuration and licenses to it. Once you have it ready to go, I would suggest upgrading only the standby controller first and  adding it to the mobility conductor. This way you may test, and move APs over by group. If this is successful, then upgrade the current active and join it to the mobility conductor.

If not:
You would want to upgrade your standby controllers first and migrate all of your configuration and licenses over. Upgrading to AOSv8 will wipe the current configuration. Any configuration in your network (controller discovery, LMS IPs for APs etc..) should not include the IP of the controller you are upgrading until you are ready to cut APs over.

Dear Community.

A have same situation: two standalone controllers (Active/Standby) on AOS 6.5 are migrating to AOS 8.9. Licenses transferred well with new initial configuration. 

But I'm afraid about HA ( configuration and license reservation between controllers) because this point missed from User Guide  https://www.arubanetworks.com/techdocs/ArubaOS-8.x-Books/89/ArubaOS-8.9.0.0-User-Guide.pdf

Does this option is present in AOS 8.9 without Mobility Conductor? 

Thanks in advance for your reply!
