870+MSM460 Mesh: Firmware upgrade

[Transport]

Hello,

Currently we are a using a mesh setup with multiple MSM460's (5).

A while ago we updated the firmware of the controller, this means all the AP's get an automatisch update also.
All the AP's, not connected through a mesh link update succesfully.

AP's connected throug a mesh link will keep rebooting.

Current workarround is to disable firmware updates for that group of AP's.

But I would like to have the firmware in line with the controller.

I can't seem to find the correct documentation to handle this situation.

Anyone who can push me into the right direction to solve this? :)

Thank you!
