Hi @chris_avellis @DTS Engineer Our team is also experiencing a similar issue as described in this ticket (where the transfer_sub exchange fails for approximately 10,000 out of 100,000 users targeted for migration), and we are currently submitting a feedback report. If this issue is resolved, it would be greatly appreciated if you could share the cause in this forum to help prevent duplicate feedback reports.

Was this fixed? Just out of curiosity I ran my script yesterday to call the Apple API to transfer users, and we are seeing way less errors - now I only have 180 errors out of the 118k+ users After seeing this post, we ran our migration script again in our environment on September 30, 2024, and confirmed that the migration of around 10,000 records, which had previously resulted in errors, was completed successfully. Could this issue have been a temporary outage?
