The background is that new feature in Domino 12.0 introduces the feature to manually upload ID's. Currently vault servers are not in 12.0 and trying to add a new vault replica. The struggle is that the existing IDvault ID is missing, so cannot perform adding a vault replica.
As an option, will be to just use the existing vault w/o an option to manual upload the ID or create a new vault and add the 12.0 into the vault servers. Hoping that there will be an option to migrate the existing ID's from old vault to a new vault if w create a new.
