When changes to the plans add-ons are rollout out only to new subscriptions (for example: when changing their price), grandfathering takes place.

To prevent a SKU sprawl, Stigg allows you to manually migrate each subscription to the latest plan and add-on version.

It's now possible to schedule subscription migrations to take place at the end of customers' billing period directly from the Stigg app, in addition to being able to trigger them immediately.
