If it wouldn't kill you, I'd suck up the time. All other solutions
are going to take additional expertise, prep, and testing.
Keep in mind that if you have tables and/or databases that don't
change frequently, you can dump those beforehand to minimize
the final downtime.
You can also put your db in readonly mode to keep it available
while the export is going on. Depending on your server layout,
(e.g. available partitions) this may or may not be worth it.
