o dump and load (if data is simple enough, you can use sqlplus to create a comma delimited flat file and sqlldr to load it -- see the web site in my url for a script that does this for you).

o exp from the source database. imp on the target database.

o create an 8.0.5 instance, create a database link to to the 7.3 instance and "create table as select * from table_at_7.3_database".

o create an 8.0.5 instance, use the SQLPlus copy command to copy the data from database to database

o perform a cold backup of the 7.3 instance, restore to new location and 'migrate' it (only works if the 'environments' are homogenous hardware platforms -- eg: SUN Sparc to SUN Sparc, intel NT to intel NT).

are some of the ways...
