Exchange 2007 to Exchange 2013 Co-Existance

Hello all

We are going to be migrating from Exchange 2007 to Exchange 2013. We are in the process of preparing our environment and have done the following according to many tutorials I have seen online

1. Upgrade Exchange 2007 to SP3
2. Installed Update Rollup 10 on the Exchange server
3. Upgraded our Functional Domain and Forest Levels to 2003

One part I am confused on is in a lot of instructions they say I must
"Recreate the Edge Subscriptions so they appear with the correct versions in Active Directory or Exchange 2013 will not Install"

a. Can someone explain this to me in laymen's terms? Exchange is showing it is on SP3 and has the update rollup installed
b. If this does indeed have to get done, how does one accomplish this and what are a step by step

I'm sure I will have other questions but this is the start

    If you don't have Edge server, you can ignore it.

    We have a single server Exchange Setup.  I look under Organization Config, Edge Subscriptions, and I see nothing in there. Am I safe to assume that this is a non-issue for me then?
