Install Oracle on new machine then build a new database with the same tablespace names as the old one. Do full export of old database and import into the new database. This is the easiest approach for small databases.

You can greatly reduce the time necessary to transfer the data if you make two exports. On the first specifiy constraints=n and indexes=n so you only export the tables (I also prefer compress=n). Then do a second export with rows=n. This will dump the constraints, indexes, public synonyms but no data. Import the first file to create the users and tables then import the second file to build the indexes and establish your constraints.

You can greatly reduce the change of any errors due to missing privileges, quotas etc... by pre-creating your object owners and granting them the necessary privileges and quotas in advance. Also if any objects depend on a grant from sys, this allows you to issue it in advance of the first import.
