Comment 1: Pictures or screenshots that are pasted to the source conversation are blob contents.

Comment 2: In migrations using the Advanced method, such migrated data in the destination cannot be previewed. If the source connection has a service account/delegated app profile, Fly will create a MigratedHostedContent folder under the destination File tab to ensure users can find those data.

Comment 3: If you select to migrate conversations as the HTML file in the migration, you need to run a full migration job to make sure the SharePoint data can be migrated; otherwise, the picture cannot be viewed in the destination.

Comment 4: After you post a picture to the source conversation and then move the picture from the current channel folder to a private channel folder in the source, after the migration, the picture cannot be previewed in the destination conversation.
