Resetting zfs snapshots

I am in the process of setting up a new FreeBSD server which involves
transferring a large amount of data onto.  The system was installed
with root zfs and snapshots were initialised immediately.

Several iterations of test data transfer and deletes has now resulted
in snapshots exceeding 64 Gb.  I wish to effectively restart/rebase
snapshots following the final transfer and eliminate all previous

What is the safest way to do this?
