Environment

2.3

Cause

The FTP password wasn't updated after a new encryption key was generated.
Such issues occur if the system was still using the old encryption logic from TCA 1.x and the FTP credentials hadn't been updated since that time.

Resolution

Update the FTP credentials on the TCA 2.3 VMs and attempt the migration again.
