Whilst not recommending export/import as the method,
I've sometimes created a migration planned that
inferred "unload-then-reload" and then post migration
used the extra time for moving objects around for io
balancing, converting to lmt's, rebuilding indexes et
al.
Sometimes downtime is hard to come by, and lying
through your teeth that the upgrade will take 10 hours
is sometimes a good way to get it :-)
Cheers
