Update asterisk if it was originally compiled from source?

Ok so I baked my asterisk installation from scratch on CentOS 6.3 x64 back in the day and I have Asterisk 11.4 installed which was compiled from source. Additionally, I’m using the chan_sccp_b driver for my Cisco endpoints.

I want to update to 11.7 but I’m not sure how to go about doing it without completely wasting my system. I have a good config backup and even a full snapshot of the system so if I toast the box I can easily replace it with the working image.

Should I just back away slowly?
