Roaming in 3 ZD

unknown

Hello!

my problem is that I have a property with 3 ZD in which to roam and testify that the SSID is the same for each of the buildings with which I have 1 ZD.
what happens to me it is that when building change devices remain suspended and have to forget the network and reconfigure it.

and I require to know is that it is possible to roam with 3 ZD belonging to the same network or solve the problem so that customers are not left hanging.

However and I opted for two solutions:
- Rename the SSID in each ZD
- Unify the network with a single controller

Or if someone can suggest me some other solution is welcome.
