I have a stack of 7 x 6248P with a firmware revision of 3.2.7.0
I want to add a new switch to the stack which wont be the master.
The firmware on the new switch is 3.3.3.3
As the new switch doesn't match the existing stack I am aware that it will start in suspended stacking mode.
Can I then 'downgrade' the firmware on the new switch from the master or do I need to upgrade the firmware on the existing 7 switches to match the new one.
