He wasn't talking about a converted system.  He was talking specifically
about restoring an Oracle backup from 5 years ago.  We are speaking
specifically about an Oracle database.  When we migrate the database to the
apply new version, there is no copy of the old version around - it has been
migrated.  And the old backups become obsolete.  And typically, the old
Oracle home gets removed.  So restoring an older version of the database
would require keeping the Oracle software around for that amount of time.
Not very likely.

The correct answer is a properly designed database that can produce reports
of what the database looked like 5 years ago - like specific account
balances.  That would be the ticket!

I see stuff all the time where people have 5+ year old systems that have
been converted, but they still keep the old boat anchor around so they can
look at stuff - sometimes to say "The old system did this, make the new
system do it!".

Between legal requirements and archival requirements, I don't think it is
strange at all that someone might want to restore to 5 years ago.  I think
it is very strange that a major database vendor might not be able to with
their primary restoration tool.
