Is there a way to "revert back to last configuration uploaded to devices"?

This is a question I frequently get when teaching the classes:

Imagine we have a fully deployed and configured network, with all devices showing a green & happy audit log icon.

We now start changing the configuration, e.g. through the configuration wizard, but at some point decide that we want to revert back to the last version installed. Or, to be more precise: To adjust the Hivemanager configuration DB to the same configuration as we have on the Access Point.

So without going through normal HMDB backup routines each time we might change something:

- Can we revert back to previous configuration version, either by Network Policy or by device?
- Can we import a device configuration into Hivemanager, e.g. into a new Network Policy, or a new revision?

Hi Carsten,

We currently do not have config rollback option.

However, one way you may be able to achieve (although not ideal) is to clone the original network policy and keep it handy while you make changes to you main network policy. Since the original policy (cloned version) has a snapshot of exactly the settings that were successfully pushed and configured on the device you can revert to that version at a later time.

Also we don't support importing network policy. I would like to understand what is the use-case or need you have in mind.

Thanks

Hi Praveen,

Thanks a lot for your explanation. Cloning the Network Policy before changing anything is for sure a good idea, but that of course doesn't back up any linked objects (DNS, NTP, Radius settings, ...), so one needs to clone every object before changing as well.

Importing an existing configuration from a device into a a new or existing network policy could be a solution for implementing a roll-back system. It would also be a nice alternative for importing a running configuration when moving a device from one VHM to another.
