Wanting to upgrade LR 4 to 6, but I don't want to use the CC. Also, I heard you can upgrade for $79?

Make sure you've got your LR4 serial number handy.
You can upgrade to LR6 without it (since you've already got LR4 installed), but you'll need both the LR4 and LR6 serial numbers for any future re-installations of LR6.
