Change advanced MR licenses to enterprise

[Azariel]

Is it possible to downgrade from an MR Advanced license to an MR Enterprise license during a renewal process? do we need to contact support for this process?

The text mentions the opposite.
But it is possible as far as I know.

Meraki MR License Guide - Cisco Meraki Documentation

*The MR Upgrade license is not a standalone license and cannot be used to license an AP by itself. MR Upgrade provides an upgrade path for customers with existing MR Enterprise licenses in both PDL and co-term licensing models.  In simple terms, MR Enterprise + MR Upgrade = MR Advanced. However, applying MR Upgrade license differs between PDL and co-term. Please see the details of using MR Upgrade licenses in both licensing models below.

I have not done that myself - but it should work.

I cannot see why it wouldn't work, as long as you have enough licenses to cover the entire network I think you would be OK, I doubt you would be able to mix and match on the same network.

As others have stated there should be no reason why you couldn’t switch during the renewal process.

If you are using co-term it is possible you will need to change the organization license tier on the AP's before you will be able to claim the new licenses.

For subscription I believe you can just claim the subscription to the org and then assign it to the networks.

Simple answer:
Buy the enterprise licenses and if you can't claim them the day after the existing licenses after they expire then shoot a call to support.

What happens to the configurations done by the AI on the RF channels and AP power, will it be restored or remain as is? Or will the Autochannel rescan again?

In most cases, if AI-RRM expires, your network will gracefully return to standard RRM functionality without requiring extensive manual intervention.
