Step 1: Update the Provider Version in Your Terraform Configuration

The first thing you need to do is specify the new provider version in your Terraform configuration. This tells Terraform which version of the SignalFx provider to use. To do this, you'll need to modify your versions.tf file or the file where you define your provider dependencies.

Open your Terraform configuration and find the provider block for SignalFx. It should look something like this:

terraform {
  required_providers {
    signalfx = {
      source  = "splunk-terraform/signalfx"
      version = "~> 9.21"
    }
  }
}

Now, update the version constraint to specify v9.22.3. It's a good practice to use the exact version number to ensure consistency and avoid unexpected upgrades. Your updated provider block should look like this:

terraform {
  required_providers {
    signalfx = {
      source  = "splunk-terraform/signalfx"
