Transfering MySQL data from one system to the other - mysql

Question

I've got all my files from my last MySQL(MariaDB InnoDB) Server and I just noticed I can't run those files on my new system. I don't have any .SQL backup of my server and my old system can't be booted to as far as I know.
I moved from Ubuntu Server 18.04 to CentOS 7 (and a RAID1 configuration), I cloned my original Ubuntu drive to a secondary drive.
Here are the files that I moved from my Ubuntu drive
/var/lib/mysql/ Files

I'm not sure what I'm missing and why it won't start, I wish I would have kept the other system to export a SQL file which would have made my life so much easier.
