There are process's with ICSF to backup the CKDS and then at a new site to
"register" the new crypto-coprocessor. However, this process involves
creating a very long "passphrase" (I believe it is even broken into parts so
that multiple individuals can each take part of the passphrase with them)
and this passphrase must then be used at the DR site to allow the
handshaking (registering?) between the crypto-coprocessor and ICSF itself.
Not pretty, and you better make sure you can read the entire passphrase at
the DR site.

And while this is a very secure method (since the key is never clear after
being registered), it is not very fast for bulk encryption. It is great of
SSL type processing (hundreds/thousands of transactions a second). But if
you think of hundreds or thousands of records per clock second during a
backup/restore operation, not very fast.
