@jackson this is currently not supported on Windows.
As a workaround, you can copy/backup all folders located under C:\Users<USER_NAME>\AppData\Local\Dremio. On Windows, Dremio is configured to look for this path for metadata by default.
@jackson After making a copy of the above directory, install the latest version of Dremio. Dremio will automatically upgrade your metadata to the latest version on first startup, which may take a few minutes.
