Migrating config file from RS5.14 backup to RS6.02

I use 2 580 Long arm ABB robots that has RS 5.14 installed. We are upgrading the paint guns to Robobell 951 in 3 weeks and I had to learn RS 5.61 but my company is going with RS 6.02. Not a huge difference but Im still very new to this. I want to use the backup from our robots in 6.02. I successfully migrated everything EXCEPT the config file. How do I go about doing it. Help please.
