Yeah, I wrote this as a little zopectl run script which anyone is 
welcome to use, just lemme know and I'll put it up somewhere.

Whoever wrote manage_convertIndexes needs a bullet through the head. 
Sheesh :-(

The catalog I was trying to update was only 15,000 objects, albeit 
File-ish ones.

The original swap death'ed the machine and I gave up after about 4 hours 
running.

My version ran in 20 mins.

*sigh*
