While this is possible, it is the least desirable way to do it, IMHO.
There at least two reasons why this is bad:

1. pointless copying takes lots of time.
2. chances are, that data is encrypted for a reason. maybe you don't want
   it store somewhere unencrypted.

With unencrypted partitions, you can simply assign a mount-point without
formatting in the installer and you get the partition mounted with
the old data.

For encrypted partitions, there should also be a way to re-use the
partition without formatting (you have to supply the passphrase, of course)
