Shut down all SQream services.

Replace your current metadata with the metadata you stored in the back-up file.
Navigate to the new SQream package bin folder.
Run the following command:

Upgrading from a major version to another major version requires you to follow the Upgrade Storage step. This is described in Step 7 of the Upgrading SQream Version procedure.
