If you want to downgrade to a previous version of the Edge software, you must downgrade to a version of the software that has previously run on your machine.

RiOS appliances cannot use an encrypted RiOS data store with an earlier RiOS version, unless the release is an update (9.0.x). For example, an encrypted RiOS data store created in 9.0.1 works with 9.0.3, but not with 9.1.

Before downgrading to an earlier software version, you must select none as the encryption type, clear the RiOS data store, and restart the service in the Management Console Data Store page. After you clear the RiOS data store, the data is removed from persistent storage and cannot be recovered.
