As part of the process of bringing a DR site online you set the
serial to be bigger than the primary site.   I suspect you would
have the DR site keeping the serial at primary + delta where delta
is big enough to swallow any changes that the primary may have made
w/o the DR site being aware.  The DR site would not supply ixfr
deltas initially resulting in a full axfr to all slaves.
