> *Background*
> As part of data migration, earlier versions of Atlas (prior to v 1.x) should be export
contents of their database to a ZIP file, that would later be imported into a cluster running
new version.
> During this process, the server should not accept any requests or process notifications.
> This process should work on an existing cluster without making it necessary to upgrade.
> *Approach*
> Create a command line utility that would perform export using core components from Atlas.
This would allow Atlas to be shutdown, so that it does not process any incoming requests or
hook messages.
> This utility should allow for using external configuration JSON so that it can be used
on Atlas setup that does not have latest version.
