Hi Everyone,
We are looking at replacing our old APs and WLC in one of our hospitals which is 24/7. We will are building an SD-Access environment in parallel whereby we will stand up new 9100 series APs and 9800 WLC.
There are many APs! I was wondering if I can clarify the approach that I think we should take when we finally get there as we can't do this all in one go.
(1) Stand up SD-Access components - ISE, DNAC, WLC, switches
(2) Migrate Wired
(3) Test 2 APs for one floor registering with the 9800s and working as expected for configured SSIDs.
(4) Migrate a floor or an area at a time for the 9800s by replacing APs physically
I'm worried about two things will the SSID being the same be a problem - This is difficult to change. Is there a best practice in doing this (e.g. swapping one out at a time.) I expect sessions to break between different controllers if people did roam and ideally we would do this 1 at a time in hours as there's thousands.
If it is possible is it better to migrate the old APs to the 9800 first to avoid roaming problems.
Thank you in advanced
JC
