So along with many others, I was disappointed when I heard Verizon wasn't announcing support for the HTC One at CTIA. So, I used the last pre-order day to get the S4. I had done some homework on the One and found that I could transfer older phone information as long as I had 2.3 Android or better. My current phone is the Droid 2 with 2.3.3. Looking at the Samsung website it looks like there is an older backup/restore software called Kies and then there is a new piece of software (being rolled out initially for the S4 only) called Smart Switch. When you look at the supported phones, you see LG Android version 2.3 or better.
