Is it possible to have the Oracle OLEDB or ODAC drivers for 8i and 10g
installed on the same machine?

If so, is there a way to select oracle home's between 8i and 10g?

I have an application written in VB6 against an 8.1.7 database. The
database is being migrated to 10g on a separate server. My client would
like to run in parallel for a few weeks entering and querying the same
data from both servers. The application has been recompiled using the
10g OLEDB/ODAC drivers and needs to run on the same machine as the
application compiled against the 8i OLEDB drivers.

I feel that I am missing something fairly basic. But the 10g ODAC
install corrupts the 8i Client install and the old application is then
unable to connect to the 8i database until all Oracle components are
uninstalled and removed from the registry.

Is there any way to make these 2 versions play nicely together?

Thanks in advance for any help.
