Can I get a little more information on this or can you point me to the documentation? I understand the freeze/copy/release part. Not sure I understand the last part. Are you saying copy the files to a completely different machine (ie. not clustered with the machines being copied from)? Are the files copied into an existing database/new database? What does the addCluster command do? Just pick up the new files?
Thanks in advance.
