I am doing a job for a customer which involves taking an 8.0.5 database export and merging it with 3 SQL Loader imports, and then replacing the original 8.0.5 schema.

The problem I have is that the 8.0.5 database is on a tru64 unix box, and I'm going to do the merge on my machine at home, which is running 8.1.7 on NT Server.

Can I convert the 8.1.7 export to load into a 8.0.5 database. If I cant then I'm going to have to load and 8.0.4 version of the DBMS and I'd rather only have one install of Oracle on my machine.

Can I run the database in 8.0.5 compat mode, and will that create an 805 export?

Is there another mechanism other than export/import. The database is going to be about 10gb by the time I've finished and some of the tables have a lot of columns with several milllion rows, so creating multiple text files for SQLloader will be a real pain.
