Hi,

How to downgrade 5520. What is the steps to downgrade it, if an upgrade for any reason (bugs or any other reason) was not as expected.

What version is the WLC on now and what version are you planning to go to?

Now it is this one: 8.10.181.3

And the plan is to upgrade to the latest: 8.10.190.0

I only needed to know how to downgrade in case 8.10.190.0 is not stable, have bugs or any other reason that needs a downgrade.

Make sure the keep a copy of the config externally before the downgrade.
