I have migrated a couple of databases recently from 7.3.3 to 8.0.4/5
(one was for designer 2000 2.1.1 which is only certified against 8.0.4)
In both cases I did a full export, created a new database including
tablespaces and rollback segments, Then did a full import. There were a
number of 'this object already exists' type errors on the import but it
all seems OK and didn't take a long as I expected.
Other DBA's I have worked with have said always do export/import if the
first figure on the version changes (ie 6.x.x to 7.x.x etc)
