Hello, same situation here.
I have a computer with x86_64_v2 CPU.
I started from RockyLinux 9.6, which Leapp does not recognized.
So I did a ‘dnf distro-sync’ to convert to AlmaLinux 9.6, no problem at all.
Now I run Leapp and it says my CPU microarchitecture is not compatible.
Obviously it wants to remain in the ‘x86_64’ architecture, which means x86_64_v3 here.
Is there any way to convince Leapp to change architecture and migrate to x86_64_v2 instead ?
