Do I need to reflash gapps when updating to the new nightlies? And should I be wiping either of the caches for best results?
Edit: nvm, flashed the new one and wiped dalvik after. Everything working beautifully.

Going from a nightly to a newer nightly of the same version (i.e. a CM10.1 nightly to a newer CM10.1 nightly), you should not need to wipe your system partition, but it never hurts if you are not in a hurry. You may want to wipe cache and Dalvik cache, as it may help to optimize the new versions of apps.
You would need to wipe your system partition when changing ROM (i.e. CM10 to stock) or changing from one version of a ROM to another version of the same ROM (i.e. CM10 to CM10.1).
Wiping cache and Dalvik cache do not uninstall apps -- so no, if you only wipe cache and Dalvik cache, you would not need to reinstall Google Apps.
But wiping system will format your system partition, deleting all system apps and user apps. This means that once you have reflashed a new ROM, if you had formated your system partition, you will need to reflash Gapps also. And reinstall all your other apps.

Do I have to wipe data and cache if I'm just flashing a new version of a kernel over an old one?
From what I understand, you can probably skip wiping data/cache when flashing just a kernel or radio. Wiping data/cache is primarily used for major changes with the ROMs being flashed.
When flashing kernels I wipe cache and dalvik cache. I only do a data wipe if I'm flashing a brand new rom.

flashed SRF 1.1.0 a couple days ago (first time rooting and all -- yeehaw!), so this is a n00b question
i know that for that, i had to data data, cache, and dalvik cache
i've also flashed the Vision kernel, which ... seemed like it didn't require wiping data or cache or dalvik cache
i've also flashed an impaled keyboard tweak and that one seemed to require wiping just cache and dalvik cache, but not data (as i recall)
so... i'm just confused, and wondering... when do i know if i need to wipe data, or just cache/dalvik, or none at all?
i just flashed the AOSP screen lock zip .. didn't see any instructions, so i figure wipe cache and dalvik, but not data (didn't want to lose my texts was my thinking)... and i just made that up. and that seemed to work. but i figure if i knew the rules of thumb, i'd feel better like i knew what i was doing
any clues / insights would be super appreciated!!
The only time u wipe:
1.
Data/Cache/Dalvik
For a rom flash that says on the rom thread wipe wipe wipe
2.
Cache/Dalvik
Is mainly when u flash themes its reccomended
3.
As for kernals and other mods unless it says to wipe then you dont need to...
Nice info so far.
After you have done this a while you can start drawing from your brain through osmosis and you will understand: if it doesn't work the way you want....EXPERIMENT.

the above post is correct, sorta.
anytime u flash something that mods /system its good practice to wipe cache and dalvik cache.
flashing a kernel, u will want to wipe cache/dalvik cache just to be safe. it prevents any sort of incompatibility between kernels.
my 2 cents
Rooted n7100 with cwm installed. Am contemplating on trying some custom roms, but installing new roms usually require wiping data. If I wipe data does it also wipe the nandroid backup I created in the internal sd? Thanks.

No, it doesn`t mate, only mostly user data. When installing a different rom wipe cache and dalvik cache, wipe data and format system. When upgrading to a newer version of the same rom usualy only wipe cache and dalvik cache unless it is a major upgrade.
Thank you very much.
I'm updating with CyanogenMod nightlies at the moment. Should I wipe data and cache each time? Won't this mean reinstalling all apps and logging back in? At the moment I don't wipe but just update each time a new version comes along.
No need to wipe data... just wipe cache partition and dalvic cache.. flash rom and gapps. Reboot.
Bit of confusion on my behalf sorry... I"m using ROM Manager and after downloading it asks if you want to update and if you want to backup existing ROM and wipe data. I sometimes back up existing so I can go back but never wipe data.
No need to wipe anything. No need to flash gapps either.

I want to downgrade my Samsung Galaxy S3 w/ the AOKP (jb-mr2) 4.3.1 ROM installed back to the AOKP (jb-mr1) 4.3 ROM. Is this possible? If so, do I have to do anything different other than wiping my cache, dalvik cache, and data before flashing the AOKP jb-mr1 4.3 using CWRecovery? Thanks!
Nope, just wipe system, cache and dalvik cache, flash ROM and reboot

I think I read somewhere that it's usually ok to just do a wipe cache, dalvik, and system when doing updates or downgrades to an existing ROM on the phone.
You want to do a complete wipe, including the above wipes when changing ROMs (CM to Stock or vice versa) for example.
No matter what though, always do a Nandroid backup or Titanium before you do anything. You never know what can happen with that pesky Android!
