Question [Q] SGH-I747 - Temp Unroot?

Hello all.

I have a rooted SGH-I747 (AT&T S3) with Android 4.1.1

When the update for Android 4.4 becomes available, I would like to have it.

I was under the impression that I would have to unroot, wipe, and install the stock to get 4.4

And then earlier I found the "Temp Unroot" and "OTA Survival" options in SU.

Will these options allow me to simply update to 4.4 without going through the hastle of unrooting/wiping ?

Thanks in advance for the help.
