OpenZFS on OS X

I currently have all my data on case sensitive ZFS pools as well as HFS+ case sensitive back up drives. Is there an issue moving the case sensitive data to a new case insensitive pool? I recall trying to do this in the past with Carbon Copy Cloner and it gave me a warning about incompatibility so I aborted it and stayed with case sensitive pools. But would there really be a problem if I had proceeded with the clone? Would ZFS send/rcv be a better way to do this?

It is warning you that if you have "Hello.txt" and "hello.txt" it wouldn't know which one to keep. But if you don't have any name clashes, then don't worry about the warning.

Thanks. I don't think that will be a problem then.
