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 Connor --- Jeremiah Wilton <[EMAIL PROTECTED]> wrote: > On Wed, 17 Apr 2002, Browett, Darren wrote: > > > The previous DBA, also used the export/import > method, and is the method > > I am most likely going to use. > > Can someone explain why anyone would opt for > export/import as a path > to do an 8.0 to 8.1 upgrade?
