MongoDB Atlas has introduced two new enhancements to its live migration feature, allowing users to import data from MongoDB deployments running in other environments and cut over to a fully managed database service with minimal impact. The updated feature now supports replica sets running MongoDB 2.6 and sharded clusters, making it easier for users to transition to a more recent version of the database software and take advantage of industry best practice security by default. The live migration tool can now be used to upgrade from MongoDB 2.6 to 3.2+, with no backend configuration, downtime, or upgrade scripting required. Users can migrate their data to a new cluster on MongoDB Atlas without having to manually configure the database version or perform any complex scripting tasks. The feature is designed to make upgrading easier and more efficient, allowing users to focus on other aspects of their applications while the migration process takes place.
