--------------------------------------
Summary: Data Migration: Create Migration Utility to Export
Contents from Atlas Server
Key: ATLAS-2461
URL: https://issues.apache.org/jira/browse/ATLAS-2461
Project: Atlas
Issue Type: Improvement
Components: atlas-core
Affects Versions: 0.8.2
Reporter: Ashutosh Mestry
Assignee: Ashutosh Mestry
Fix For: 0.8.3
*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.
