I think you want: Remap_tablespace=USERS:TABLESPACE_1, ADIFFERENTTABLESPACE:TABLESPACE_2, etc etc. You can't remap a tablespace twice.

I also tried with semi-colons (;) and spaces as delimiters between the multiple tablespaces, each time receiving the error above. Would someone tell me how to use this particular piece of functionality or point me in the right direction? it would be: remap_tablespace=original_tablespace:target_tablespace. If your target schema is different too, you have to use: remap_schema=original_schema:target_schema. I'm spanish, I'm sorry for my bad english. I hope that you can understand me. Cheers...
