The problem with that is that you cannot remap schemas and tablespaces
in a single datapump or exp/imp operation. I can do one or the other.
I am in a situation where we need to allow the users to do both, which
means that it is clearly a post-processing step. If the users migrate
all tablespaces for a particular schema we can rename the schema as part
of the operation and then rename tablespaces in the post-processing
step, but if they only bring over one tablespace out of 12, and rename
that and also want to rename the schema at the same time, the
datapump/exp operation is at the tablespace level and the schema needs
to change in the post-processing step.

I've never tried that method, and wouldn't advise it on a production DB.
The supported method is to use exp/imp with fromuser/touser, or
expdp/impdp with remap_schema.
