A upgrade from 6.x to 8.x will required a re-configuration of you controllers. After the upgrade of a controller it will be factory reseted.
Approach could be (in short):
1. Install a virtual Mobility Conductor (recommended to us this and buy a license for it)
2. Remove one 7210 (standby controller) from your production.
3. Bring one 7210 controller online and configure the setup.
4. Use the LMS IP configuration of the old controller to move APs from the old to new controller.
5. After anything is run on the new controller, breakdown the old master controller, update it and join it to the new cluster.
Its correct that the AP-225 will run in ArubaOS 10.8.0.5, mentioned this is the latest major release that will support them and this type AP will end-of-support this year.
Best ask your local Aruba Partner to help you with the migration.

I would recommend the AOS Fundmentals Guide
https://www.arubanetworks.com/assets/tg/TD_ArubaOS-8-Fundamental-Guide.pdf
In that Guide you will find Migration Strategies as well.
You cannot mix Hardware based Controllers with virtual ones in one AOS8 Cluster. You have to create 2 Clusters - one with 7210s and one with the virtual Controllers.
The Mobility Master - or now called Mobility Conductor - can be virtual without any issues.
Latest 8.10.0.x - as of now it is 8.10.0.5 - is a good Release to go to.
Be aware that this is no "traditional" Upgrade it is a Migration. Best would be to save the existing Configs (encrypt disable before saving config!) and Flashs.

Subject: Migration from AOS 6.5 to AOS 8
I am preparing for a migration strategy from AOS 6.5 to AOS 8. I currently have two Controllers 7210s and the APs are a mix bunch of 225s and 335s. We have 210 APs.
To my understanding AP 225s are supported up to AOS 8.10. I am thinking of virtual mobility masters and virtual mobility controllers but since the 7210 controllers are supported for many years to come I still want to use them. So my guess is that it will be a mix of virtual mobility controllers and physical 7210s.
After migration I will upgrade AP 225s to AP 535s as they are going to be end of support in Feb.
It would be good to have some suggestions for high level migration strategy.
Thanks a lot!
