Maintaining dblink between databases after upgrade

I am currently using an application which uses the Oracle 8.1.7 database. This application also fetches data from another database which is in Oracle 7.3.4. The interfacing between these two databases is done by Pro*C programs and Perl scripts. Now the 8.1.7 database is getting upgraded to 9i. But the dblink between 7i and 9i is not supported. So what could be done to maintain the sync between the 7i and 9i databases, including the changes to be done to the Pro*C programs and Perl scripts if any?

One of the tricks I've seen employed is to create an 8i database in the middle. The 9i database link points to the 8i database. Any object in the 8i database is really a synonym which points to the 7.3 database through another database link. I do not recommend this approach unless absolutely necessary. I would rather upgrade the 7.3 database to a supported Oracle version.
