i have a question regarding a Controller-Migration, from C5110 v9.21 to C5210 v10.31.
Right now the Controllers a running in a HA-Cluster(C5110 v9.21). We want to migrate them to a C5210 HA-Cluster(v10.31)
My question is regarding the migration what is the "best" possibility to migrate the Controllers.
I already got the configuration from the C5110 to the C5210, so the have the same Config.
Is it possible first to change the Backup-Controller to the C5210? Is it possible to have two different Controllers same HA(with different Versions)? So i can switch the APs to the new Backup-Controller and than change the Primary, if everything is successful to switch back to the new Primary-Controller?
Or is it just better to install the new Controllers, deactivate the old one and activate the new Controller Pair? So the APs should connect to the new one.
And yes all APs are supported, with the new 10 Version.
I hope my question is understandable.
If there are any question please let me know, or there is a better solution.
