I have a large data warehouse running under I want to transport it and upgrade to 10g on another server. What is the easiest way to move the data (on Unix)? It is too large to export/import? Thank you.

Have you looked at Transportable Tablespaces (TTS)? With TTS, you make the tablespaces READ ONLY and use the exp utility to create a small metadata file describing the contents of the tablespace. You then copy the tablespace's datafiles and the metadata dump file to your destination server. On the new database you plug in the TTS with the imp utility, but this only takes a minute regardless of the tablespace size. Look in the Oracle docs for more information on TTS.
