Upgrading Active Vaults

Active Vaults are a discontinued feature with a different upgrade procedure.

To upgrade an Active Vault:

1. Import the server share onto a third device

2. Initiate upgrade from other devices

3. Join with all three devices

4. Complete upgrade

The result is a standard Secure Vault without Vultiserver involvement.

If Fast signing is still desired, create a new Fast Vault after upgrading.
