SymptomsWhen trying to run the pre-migration Helm3 Compatibility Checker before performing migration from Helm 3 to Plesk 10, the following warning is shown:
Plesk doesn't support empty subscription. (Package will not be migrated)
CauseThis issue occurs because Plesk does not support empty subscriptions.
Helm allows users to create packages without domains and then, create domains later. However, in Plesk, a subscription always has a main domain.
Empty packages will not be migrated.
