Above procedure and table is best practice to export and import but also consider below case.

Dumpfile exported in Oracle 11gr1

Import in 10gr1, 9i, 8i

Then use Oracle 11gr1 client (IMPORT) binary to export 11g dumpfile.

Install oracle 11g client and connect to 10g,9i,8i server and import.

Dumpfile exported in Oracle 10g

Import in 9i,8i

Then use Oracle 10g client (IMPORT) binary to export 10g dumpfile

Install oracle 10g client and connect to 9i,8i server and import.

Dumpfile exported in Oracle 9i

Import in 8i

Then use Oracle 9i client (IMPORT) binary to export 9i dumpfile

Install oracle 9i client and connect to 8i server and import.
