AlmaLinux 8 CWP -> AlmaLinux 9 CWP Migration

OK, there have been allot of threads about this, but can't find the answer.

Yes, even I get stuck.

Trying to migrate AL8 CWP to AL9 CWP and won't connect.
Firewall is OK, and I can manually SSH in to old server from the new one with root & password.

The secure log on the old server shows trying the migration tools:

Dec 17 06:33:05 x sshd[41722]: Accepted password for root from x.x.x. port 55614 ssh2

Who & what got this working?
@overseer?

Sorry, I'm still in the conservative EL8 camp. Maybe I can spin up an EL9 VM and give it a go, but you're still ahead of me...

Does the password contain some special chars like "!@#$%^&*()_+" ?

No, just letters & numbers.

What's odd is I can SSH from AL8 -> AL9 without it prompting me for a password (Did a key-swap trying to get this to work).
But from AL9 -> AL8 even with a stored key it asks for the root's password. I enter it, and I'm in.

I thought this bug was fixed in .1188 or the current .1189

 

Just tested CWP -> CWP Migration from another AL8 box and it works fine.

So there's a bug somewhere connecting from AL9 -> AL8 with the migration tool.

Maybe @josemnunez or @Sandeep can shed some light on it, or a workaround.
