I would think from the original question, the recommended way would be to add Mobility Conductors, but you mention that the customer is not willing to invest in those.
AOS10 with Central handles roaming in a different way without Mobility Conductors, so that may be an alternative in your case.
In an architecture with 5 controllers on a single site, there is a form or coordination needed to guarantee good roaming, which has basically 2 options: Mobility Conductor (AOS8) or Central (AOS10). Moving to Instant is a theoretical option as well, but if you have 5 controllers, you probably have at least 100s of APs, in which case controllers/gateways are recommended for the scale.
You may work with your Aruba partner, local distributor or local Aruba Sales team to discuss your options in detail as the above is a generic guidance, not specific for your situation.

Hi Herman!
Tks for your help. In this case, I can't use Aruba Central.
Can I solve it, using only AOS10?

Building a cluster under a mobility conductor would be the solution to this challenge on AOS8. With AOS10 you could so the same with Aruba Central taking care of the similar function

I have 5 controllers, working on the same site, but the person who did the initial installation installed each one separately, and this is causing roaming problems. The customer does not want to buy the Mobility Master or the Mobility Conductor, is there any documentation on how I can solve this problem using the Master Local, or Master/Slave, resource?
