Switching from Vivint - keep panel?

I found some articles about take over kits but they look to be for the older smaller display touch screens. What do I need to do to switch from Vivint to Surety with the larger panel? Also, I have two secondary panels attached to this system… anyone know if those are vivint only as well (installed by Vivint) and will need to be replaced or are these something that I can actually take with me?
