Confluence DC to Cloud. We strip page restrictions before the migration and put them back after.
The preview note says an app can access data from “restricted spaces that are part of the migration”, including spaces “restricted to a specific set of users or groups”. The word page does not appear anywhere on that docs page. CHANGE-3287 says spaces too.
RFC-122 started elsewhere. The scoping proposed there was per page, a macro on a page meaning access to that page. In January it became unfettered access to the restricted spaces.
And MIG-837, which is about page restrictions and the 403 an app gets on them, is closed as Fixed on the back of it. Elliot from the app migration team called the preview “restricted confluence page data” there.
Which is in scope in the migration window? A page in an open space, own view restriction, app user not on it. Readable? Writable?
Have not found anyone who has tested it since July.
