We are migrating from a commercial cloud to a government cloud. Our office 365 vendor did a delta sync so all of these sites are now be moved over to the new tenant. I have created a flow that "should" populate my plans with the tasks. Regardless, I have found many discussions and a script that will help me populate my plans.
Our vendor can do another delta sync of the SharePoint sites, but I’m wondering when they do that sync, would I have to “reconnect” any of the Planner sites again? Will syncing over a previously migrated SharePoint site that is associated with a plan break the connection to the plan after I have populated it with the tasks?
