I think we are slightly moving off-topic here. The original poster wanted
to compare the various speeds of the methodologies, not if the
methodologies themselves were do-able.
Using RMAN may or may not represent a time-savings from his original
intended purpose - to move the data fast with minimal downtime - because
it will REQUIRE you to keep the source database tablespaces in READONLY
mode while they are:
1) Being Backed up
2) Being moved across a network, perhaps
3) Being restored to a new target.
Since an endian change is being made, archive log application methodology
is out of the picture.

If you are on Oracle 10gR2, it is more easily to convert the database
across platforms using RMAN. I have done this quite few times and
succeeded.

Hello,
We are doing a database migration from AIX to Linux. Our database is
600gb. Has anyone used the rman convert database method to migrate the
database? Do you have any timings you can share, especially compared to
expdp/impdp? Unfortunately, I don't have the luxury of time to try it out
myself.
Thanks in advance!
Haroon
