RE: Upgrade 8.0.5 to 8.1.7.3

I also remember (hopefully correctly) reading somewhere, either in metalink or from
this list that there is a "low-level corruption" problem in 8.0.x that may causes problems when migrating to 8.1.x, by doing the imp/exp method, you don't have to "fix" the 8.0.x database before you upgrade.

There was a script supplied by oracle that you can run to verify the database before you migrate/upgrade it.

Clean up fragmentation/chaining, change block size at the same time, in my current
case, chage hardware platform...

All sorts of reasons. :)

Can someone explain why anyone would opt for export/import as a path to do an 8.0 to 8.1 upgrade? Doesn't the basic upgrade just consist of starting the instance on the new ORACLE_HOME and running an upgrade script? Why would someone undergo the disruption and complexity of a full export/import when you can just leave the data where it is?
