Reduce export import time

Question

Hl All,
I want to reduce the total time spent during export-import.
Restrictions:
=========
1)Cross Platform
2)exp and imp from lower version to upper version
3)No 10G database
Basically i want to do exp and imp in parallel so it reduces the total time spent on this activity. I thought of doing schema level exp-imp in parallel but i am afraid of the dependencies.
Is there any other way to achieve the same or if i go with the above specified approach, can anyone provide some valuable inputs to that.
I am trying to automate the above so that it becomes one time effort and rest all the times it(script) should do at his own.
Thanks and regards
Neeraj

Hi All,
Data volume is not less than 60GB and not more than 150GB.
If i use a pipe on unix in between exp-imp what if my exp is slower at any
point of time and import is faster(Any reason)?
is import going to wait for the contents coming into the pipe through export or import will fail.
I can consider creating indexes using the flat file.
is there any way to get only the indexes in the flat file, i mean if i use indexfile
option for import it gives me "CREATE TABLE..." statements too which means import utility is reading full
dumpfile and giving me the output, i want only the "CREATE INDEX..." statement in the flat file.
What about the schema level export and import?
Any valuable inputs or proper steps from anyone out there
Any restrictions while importing the schema's.
Thanks and Regards
