I moved from iPhone 12 Pro to iPhone 13 Pro using Apples device-to-device option. Most of the apps migrated to the new iPhone with all of the on-device content.
For DEVONthink, iCloud (CloudKit) syncing was deactivated on the new iPhone. I had to re-enter my sync key. I then had to re-download the ~30k items.
Is this by design? My expectation would have been that DEVONthink migrates to the new iPhone along with all of the content from the old iPhone.
