Hi Guys,
Have been happy with Ventura and unhappy to find later systems offer features which are irrelevant to me, irrespective of what Apple say about security. I reckon complexity adds vulnerability and I use a variety of tools to keep watch.
Migration Assistant no longer working for Ventura 13.7.8 (22H730) Is there a fix?
Introduction
I decided to try Sequoia on my 2019 iMac and found it a very unpleasant experience. Security demands password for opening AND a password for approving application function. Very tedious. Doubles keystroke work. I decided to stay with Ventura.
My iMac uses a 2TB SATA ssd with Sequoia, and a 2TB NVME ssd with Ventura 13.7.6. Normally I would simply erase Sequoia, Use Restore on the NVMe to download Ventura, then use Migration Assistant to restore user account and settings.
Problem 1
Opening the Ventura on NVMe hit a Kernal Panic. Past experience has shown the only solution is erase and reinstall.
Time to think carefully.
We know Apple discourages using earlier systems and forces users to upgrade to latest offerings in the name of security. We also know that the only way I could reinstall an older o/s is by using Restore via Internet which gave the original o/s supplied with my machine; in this case Mojave, then build forward to desired o/s.
I downloaded Mist which allowed me to download Ventura Disk Image and package. I opted for Ventura 13.7.8 as the latest version. Big mistake!
Problem 2
I downloaded Ventura 13.7.8 to a 4TB external ssd using Restore. Once the o/s was installed with Apple ID etc. I attempted to transfer apps and settings. Could not be done! Migration Assistant did not recognise Ventura on the NVMe stating. So Migration Assistant would not migrate data on 13.7.6 to Ventura 13.7.8 backward compatibility issue? I would not have thought the kernal panic - a bootup issue, would effect Migration Assistant but then I know very little.
Reconsideration
I decided to Use CCC to transfer Account settings to Ventura 13.7.8 on 4TB external and returned to Sequoia to export browser settings and passwords onto USB and thense to external 13.7.8. This worked and I had a clean operating system but needed to install apps. I tried Migration Assistant again - no recognition. So I installed 34 apps one a time, activated and registered them as necessary.
Data transfer without Migration Assistant
Now I deleted SATA Sequoia, installed Ventura 13.7.8, via Restore. Migration Assistant would not recognise Ventura 13.7.8 on external drive so I transferred User Account, apps and Settings manually with CCC or USB.
Once this was completed I erased Ventura 13.7.6 on NVMe (and kernal panic) then reinstalled Ventura 13.7.8 via Restore. No more kernal panic, all operating properly. However Migration Assistant still would not recognise either of the other two available drives with Ventura 13.7.8 for migration. The screenshot below shows Migration Assistant still does not recognise either of the other two drives one internal, one external, as accessible for data transfer.
Having encountered obstruction from Migration Assistant at every turn, having spent four days jumping hurdles I have three un-synced OSX 13.7.8 which still cannot use Migration Assistant.
It seems I should have stayed with Ventura 13.7.6 instead of upgrading.
Research
A recent article led to these comments by Mike Bombich

The article confirms the importance of Apple ASR combined with the Recovery mode environment and Migration Assistant, so that makes the Migration Assistant behaviour I experienced even more inexplicable.
I ask, what went wrong? What am I overlooking?
I welcome any contribution which sheds light on this incident.
