Root migrating data from Razr to Razr Macc

[droidster333]

Hi, newbie here. I'm trying to migrate apps data from a Droid Razr to a Droid Razr Maxx. From what I've been reading, this is simple to do using Titanium Back Up, but I need to root both phones. I've never rooted a phone before, but just techie enough to give it a try.

I've been trying to find the best way to root the older phone and have seen mixed information about what is needed or possible. The Razr is running JB 4.1.2. The build is 9.8.20-72 VZW-16-5. How do I figure out if it is an xt910 or an xt912? Does that change how I go about rooting the phone? I have an iMac, but can get access to a Windows laptop if needed. It would be great if I didn't need a computer.

Thanks for any help you can provide.
