We currently have over 150 staff connecting via 15 x MR33's successfully, we intend to open another floor that will have around 100 staff and we are looking at purchasing MR46's as these are only available to us due to supply. I have read that we are able to run a mixed network, are there any procedures I need to bear in mind, level of firmware needed? Currently we have in place 1 x MX100 running 15.44 - upgrade is planned to go to 16.16.2 15 x MR33's running 28.6.1   We will purchase new MS210 switches that will/should have 14.33.1 loaded.   Any assistance on what I need to be aware of and firmware I need to run across both floors will be greatly welcomed   Thanks, Iain  ...
