there are a couple of ways to move the installation across.
One very simple way is by ,as already has been mentioned, shutting down cache and then copy the cache.dat files across for example using ftp.
Another way is using the build-in backup utility to take a backup and restore the backup on your new system,. this does not require a shutdown of cache on either side.
Also make sure you grep a copy of the original cache.cpf file as this contains all the database,namespace and mapping information.
