Ed brings up an interesting question. So with your response, you're saying that with PPRC, you cannot 'reverse' the mirror. Breaking and re-establishing the mirror pairs will require a full data re-push back to the now secondary site.

When are all replicated and almost up to date, shut down the primary, wait for updates to propate, and start at the secondary. XRC may be a bit different.
