Is there a switchover cluster function in 3.62? I am trying to move legacy Aps to a 5.2 cluster from a 3.6 cluster. For some legacy reasons I cannot upgrade the 3.62 yet.
The 5.2 cluster was upgraded from another 3.6 cluster. hence a zone based on 3.6 can be created.
We use a combination of 2 BASH-scripts in linux combined with an IP-list that executes the following commands;
IE. 1st script contains login-information to the APs and calls the IP-list (txt-file one IP per row, which then calls the second script that executes the commands.
set scg fullreset
set scg ip [IP-adress1,IP-adress2,.....]
This works flawlessly in 95% of the cases on first attempt, AP´s not migrating to the new controller, we simply run it again with a new IP-list.
Worst case if something has not come over successfullyt we do it manually. Migrated 900+ AP´s with this script in batches of 20 aps´s per batch. Did not take to much time.
We use the same method to for instance set tunnelmgr IP´s and so on depending on what dataplane we want to put workload on.
