Hi all forum pro:s
I have a mix of 225, 505, 535:s. I am on version 8.6 as it is the latest I can have in the controllerless cluster. The upcoming week I will replace the last 225 with a new 535, which means I am no longer bond to firmware version 8.6 and can upgrade to 8.7, 8.8, 8.9 or 8.10.
Any one that knows if there is a significant risk to upgrade several major releases at once (i.e from 8.6 directly to 8.9 or 8.10), or if it is better to upgrade one major release at a time?
Many thanks in advance
