You don't have to create a new context, but you'll need to:
delete all rules 
repopulate context with rules you'd like to keep
build context.

Or as you said - just create new context, populate it, build, destroy old one.

Yes, in theory up to 64 fields allowed, though on practice I never used more than 11 so far.
