I have been playing with wave export/import tool and it works great and of
course it allows to move then from disk to mongodb. But it only exports
those waves of the user we use to execute the tool. So from an
administration point of view I can't perform a full dump of waves.
Does anybody know if there is a way to perform a full export of waves?
Thank you!
