I just got my PBP 3 setup and I'm about to install it. However, this situation makes an old healed-over software tools injury itch.

I was using MPLab 8.60 and PBP 2.60a. I have a substantial code base, including some stuff I need to compile without spending a week sorting out tools compatibility issues.

1. Does installing PBP 3 require disconnecting/uninstalling PBP2.60a? That is, can I leave 2.60a there as a fallback?
2. I believe PBP3 will successfully compile programs which compiled correctly under 2.60a. Is this correct? (that is, make me feel better )
3. Can I plug PBP3 into MPLab 8.6 without also having to upgrade MPLab, thereby violating the rule to never change more than one tool at a time?
4. Assuming 1, 2, and 3, can *both* PBP3 and 2.60a be plugged into MPLab and selected as alternate language suites?

I appreciate any pointers.
