I find myself having to move a database between hosts but at the moment don't have the option of upgrading or downgrading any of the hosts.
I'm trying to find out if it is safe to do the following:
I have a running mongodb 3.0.15 instance which I've taken a dump from. I've restored that to another mongo instance running version 3.4.4 without any issues.
Can I now take a dump of the data in 3.4.4 and restore it on 3.0.15? There has been no material change to the db besides the usual create/update & deletion of records while running on the surrogate host.
