p2v nightmare stuck at 97%

Hello,

I have been trying to get our onsite RHEL 10.0, which hosts our Mitel Voicemail, to convert via the VMware vCenter Converter Standalone Client 6.2 as we now have Veeam and we would like to back up the system accordingly.

The issue here is that when I run the converter, we get all the way to 97% and it craps out with this error stating "Partition number must be set for the boot volume"

As far as I know, when the new VHDD gets made at the destination VM the UUIDs and such get broken as that physical hardware is no longer there? and thus I can not boot from the new VM(this is only a guess) because it doesn't know where any of the FS are anymore, so I concluded I may need to create a new fstab and grub, but I have absolutely no idea how to go about doing that? Or that the p2v software is not starting the raid software to reconfigure the raid when it arrives to the new VM?

So, since I don't have RHEL 10+ .iso, and the old RHEL 9 .iso kernal is too old to rescue from, I took a CentOS.iso and booted into rescue mode.

Can I please have assistance on how you might go about doing this?

Another idea I had was to go to the Mitel server and undo the Raid on the software controller and set it to just one /dev/sda and run the conversion again so it tries to reconfigure with only one but I also don't know how to do that, and since it is currently in production I am afraid it'll break and then I'll have to recover two things! How do I do a full safe backup on a live server?

Help? I am open to all suggestion, provided you can explain to me why, please and thank you.
