Not enough Space on AP Device

Hello everyone,

i want to update may capAC’s to the latest Version ( from 7.10.2 to 7.11.2 ).
But the issue is, there is not enough Space for it ( see ScreenShot ). I’ve tried the NetInstall to free up the Space, but no effect.
Any idea’s to free up the space / or remove old firmware files, which are not grapable?

There have been quite some reports about issues with netinstall on 7.11.2

Try latest ROS6 and then upgrade again to 7.
Or latest 7.12rc.
