I have two databases, Oracle 8.0.4 on Tru64Unix and oracle on Linux 8.0. I have a full export of oracle 8 DB and want to import only three users with object in to 9i Database.

Can I use full export dump of Oracle 8 DB or i have to first take user level export of 8.0.4 DB and then use fromuser, touser parameters ?

What other precautions i have to take before doing this operation ?
