The only time I've actually heard a manufacturer's rep address that question in a technical committee meeting he recommended not using the old fastener holes, but rather to fasten through new locations. That was USG for Durock.

And if you're gonna remove your wallboards, I'd recommend you remove the moisture barrier entirely and use a direct bonded waterproofing membrane over the entire interior of your walls and kill all the birds with that stone.

My opinion; worth price charged.
