What Is the best (safest) way to unjailbreak my iPad 2?

[iMore Question]

I have a jailbroken Verizon iPad2 software version 6.0.
Unfortunately due to computer crash I no longer have my iPad restore file in iTunes to do an "easy" unjailbreak.

I would like to unjailbreak it and move to IOS 7x (which I understand can now be jailbroken).

What Is the best (safest) way to unjailbreak my iPad2...

1. Install latest IOS 7 version (which I assume will overwrite and clear the current jailbreak) or
2. Do an IPSW Version 6 firmware flash instead?

I'm not concerned with saving content but I would like to re-jailbreak with IOS 7x after I get it restored.

Thanks

DFU restore with iTunes to iOS 7.1.2 is the easiest method of unjailbreaking
