Important
As of February 2025, you can create Flex clusters, and can no longer
create M2 and M5 clusters or Serverless instances in the
Atlas UI, Atlas CLI, Atlas Administration API, Atlas Kubernetes Operator, HashiCorp Terraform,
or Atlas CloudFormation Resources.
Atlas no longer supports M2 and M5 clusters and Serverless instances. As of May 25, 2025, Atlas has migrated all existing M2 and M5
clusters to Flex clusters.
Atlas migrated Serverless instances to Free clusters, Flex clusters, or Dedicated clusters according to your usage. To see which tiers Atlas migrated your instances to, consult the All Clusters page in the Atlas UI.
Use the following resources to configure and manage your Flex clusters.
