I can send you logs from all migration attempts, fortunately, for I relocated log file(s) to flash memory, where they survive reboots

If I understand it well, log file from last migration attempt is messages.1 (dated Jun 17 04:35); of interest maight be times from 14:25 (shutdown - reboot) or even later, 14:33 (pkgupdate).
As far as I don’t know how to send it to you directly from Omnia, I can unplug flash drive and hopefuly send the file using Windows 
Edit: better I generated diagnostics by Foris (renamed messages.1 to messages…). Mailing it to support.
