Using deprecated host classes in Managed Service for MongoDB

Starting January 1, 2024, the b1.nano, b1.micro, b1.small, b2.nano, b2.micro, and b2.small host classes are deprecated for Managed Service for MongoDB.

What this means for you as a user:

• You will no longer be able to run your cluster if it uses the b1.nano, b1.micro, b1.small, b2.nano, b2.micro, or b2.small host classes.

• If your cluster uses hosts of these classes, you will not be able to add new hosts of any class to your cluster.

  To add hosts to your cluster, first change the host class to a supported one, for example, b1.medium or b2.medium.

• You can restore a cluster from a backup only to existing host classes.

  You cannot restore a cluster from a backup to b1.nano, b1.micro, b1.small, b2.nano, b2.micro, or b2.small hosts even if the backup was created from a cluster consisting of such hosts.
