> *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.
