MBT -> GPT to reuse existing installation

Good morning.
I had a working system using a old linuxcnc version (+- 5 years old). It was running fine, but the motherboard needs to be replaced.
I was unable to boot the same SSD on the new motherboard, so I suppose that from what I have read that the issue is more likely because the current installation was done on the old MBR.
The new candidate motherboard only has UEFI so for what I have read, I must convert the current disk to use GPT.

I have read some online information, and there are many steps involved on the conversion. Should I try to start from a new installation or still the conversion would be less trouble. What is your opinion?

Thank you for the reply.
I did what you suggested, before my post, and the motherboard does not recognize the SSD. Strangely it displays a very fast message that I was able to see:

There is no vBIOS support detected in this card.
'BIOS CSM/UEFI Mode' settings in BIOS will be changed to 'UEFI'

and automatically it moves to the BIOS screen, and the previous changed settings are converted to UEFI again.
Note that I do not have a separated graphics card.

The issue is that the disk is not listed there.
Motherboard is MSI. I will try something else later today, but does not look promising.

Use a new SSD.
Bookworm is pretty good with UEFI but I think I would try installing Trixie to get any later enhancements now there is a beta ISO release
You should be able to install Linuxcnc with:The dev package installs halcompile etc
 

Probably I will start with a new installation. Downloading Trixie now.
I think I will need help in "moving" the old configuration to the new one. I will post when help is required. Thank you

I did some research about the uspace and the general information is: uspace is not intended to control real machines, but used for simulation.

This is still true? Because if it is, I cannot use it as the intention is to really control the machine that was previously working.
Thank you

"uspace" in this context means using a Preempt-RT kernel.
(rather than RTAI or some other real time kernel)

The Debian linuxcnc-uspace package includes the PREEMPT_RT kernel as a dependency so there should be no need to install anything else.
These new distros can be  a bit problematic. my notes here should solve any latency issues.
