Unable to restore from backup "Project.db.######" files

Hi, I am a noob and just got DaVinci Resolve Studio DRS17.1 activated.
I was using the Beta version and saved what I thought were backups.
But I guess what I thought were backups are not actually backups.
The files the DRS17.1 finder is going for are *.backup or *.diskdb files but the only backup files I have are Project.db.* files.
I had to sell the old computer to get this one and thought I had copied all I needed from the old computer.
Did I screw up?
Is there a way to recover them or perhaps convert them?
I am trying to follow: https://beginnersapproach.com/davinci-r ... -projects/
But am getting a little confused partly because it doesn't give Linux instructions.
Are these correct directions?
He starts saying that I might have to get the project.db file to be converted to .drp here on the forum???
Please LMK. Thanks.
