Migration fails on the
transfer-accounts step with the error like the one below:
+Subscription 'example.com' error: Subscription is assigned to hosting plan 'Linux Basic Hosting' that has not database MySQL service MySQL service should be enabled in hosting plan in PPA
Subscription has MySQL databases on the source server, but service template "Linux Basic Hosting" in the PPA has no such resource. Migration manager does not know where to migrate MySQL databases from the source server and fails.
Check service template mentioned in error and add the "MySQL database" resource to it.
Restart the migration.
