I think what he means is that in 10g there is no O/S limitation in regards to using Transporatble tablespaces and one of the limitations is that you cannot transport the system tablespace. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Bobak, Mark Sent: Wednesday, January 11, 2006 2:17 PM To: JBECKSTROM@xxxxxxxxx; oracle-l@xxxxxxxxxxxxx; oracle-db-l@xxxxxxxxxxxxxxxxxxxx; ORACLE-L@xxxxxxxxxxxxx; oracle-rdbms@xxxxxxxxxxxxxxx Subject: RE: migrate database Jeffrey, I think what you're thinking of, is that starting in 10g, you can migrate a database across platforms via RMAN, avoiding the need for exp/imp. Not sure what you mean by "migrate the system tablespace". The idea is to migrate the entire database from one platform to another. -Mark PS I've not yet tried this, only read about it..... -- Mark J.

I am no longer able to find a reference supporting this. Can you migrate the system tablespace in R2??
