    Okay so I just installed RA 2.3 and I see new options in the wipe section, do I need to even worry about these or will I be fine just doing the regular data, cache, and dalvik wipe while flashing a ROM? The new options are boot, system, and SD card, I know I don't need to wipe my SD card to flash a ROM, I'm just not sure about the other two.

    Basically, when you wipe data/cache/dalvik, your current ROM still exists, and you can even boot up. What you essentially did was a factory reset for your current ROM. If you have a custom ROM, you'll still have it, but with stock apps/settings. The reason is that the ROM exists in /system. /boot contains information necessary for the ROM to boot up (kernel, etc.). When you flash a ROM, it's overwriting what is in /boot and /system, and generally not touching /data. You have the wipe /data because there can be major conflicts with what's in /data with a new ROM. So, when you wipe data, you're not wiping out the old ROM; you're just hoping to eliminate data/settings conflicts. In order to actually wipe the old ROM before flashing a new one, you must wipe /system and /boot. Up until RA 2.3, you need to flash calkulin's Formal All zip, which would wipe /system and /boot. Is this necessary? Well, maybe. It's recommended, especially when switching between Sense and AOSP, and vice versa. Do most people do it? No, not really. If you have a problem with a new ROM, consider wiping /system and /boot. Otherwise, you should be fine not doing it.

    Okay so I don't "need" to wipe them but if I have problems with the new ROM I should go back wipe then reflash. Now I am probably going to flash CM7 so should I write going from Mikfroyo?

    It can't hurt to wipe /system and /boot each time. You can just add it to your routine. If you've been using previous versions of RA without using the format all zip, you haven't been wiping system or boot, anyway, and likely haven't had any problems. That being said, it's probably a good idea to do it if switching to CM. Also, never wipe /system or /boot if flashing a ROM that requires an already bootable ROM to be flashed (these are rare, but I've seen a few out there).
