When we went from 7.1.4 to 7.3.2.3 we used a full export (as per Richard
Woods). On the export side, set compress=N. One possible hint: because
the machine architecture was changing, we precreated the (old)
tablespaces on the new machine under the new directory layout; also
changed our rollback segments in accordance with the OFA. Then dropped
some schema owners (fixed data that we would generate later) This caused
some errors in the import log but we ended up with what we wanted. The
project has a number of similar databases and if, somewhere, someone
might forget to drop a particular schema, no problem, the susequent
import for the schema would fail because the corresponding tablespace(s)
couldn't get created (because the directory paths didn't exist - just
what I would have wanted to happen, although I had to pour through a
lot of errors to convince myself of that, including one awlful sounding
one to the effect of unrecognizable data). You'll also see errors on
already existing errors in the system tables.
On the import side, DESTROY=N and ignore=y.
