Unofficial to Official ROM - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hello all!
I've got an unofficial version of a custom ROM installed on my phone and I want to migrate to an official nightly version of the ROM. Can I flash the official version over the top of the unofficial version, or do I have to do the full memory wipe process and treat it as a completely new ROM?

[Q] Baseband version - Cyanogenmod

Hi,
I'm currenty using CyanogenMod 10, probably switching to CM 10.1 when SakuraDroid RC1 releases.
My current baseband version is XXMF1, I see that XXMG2 is the most recent one.
Is it good practice to always update to the most recent baseband? Or is it ROM-specific what the best baseband version is, and should I ask this question on the thread of the ROM I'm using?
How do I go about only updating the baseband version without flashing over my CM firmware?
Thanks
Yes, it's good to upgrade to the new baseband if there are changes in changelog - but there no way to upgrade it without flashing. Just go ahead and install new firmware, and next CM.

Recommendation

Hello all, I am currently on aosp Candysix rom and am experiencing major BT connectivity issues. I would like to go to a stock rom that is based off of 6.0 (marshmallow). Can any recommend any roms that have very few issues and can be used as a daily driver? Thanks
Also, with the rom you recommend, can I just do factory reset, wipe caches and flash coming from candysix and I have twrp 3.0.0 installed will it work with that version?
