Upgrade cluster version from 3.6 to 4.0

[yx2387]

Hi all,

I tried to upgrade my cluster major version from 3.6 to 4.0 with terraform, but the cluster is not upgraded after terraform apply.

Terraform plan:

Terraform will perform the following actions:

  ~ module.app.module.mongo_notification.mongodbatlas_cluster.cluster
      mongodb_major_version: "3.6" => "4.0"


Plan: 0 to add, 1 to change, 0 to destroy.

I tried to do the same with Mongo API and it works fine.

I've hit the same issue going from 3.4 to 3.6.

Same issue when I tried to upgrade from 4.0 -> 4.2

This is the log that I see, but nothing changes in atlas
