To install the new provider version in an existing Terraform project, which command should you run?

• A. terraform init -upgrade
• B. terraform apply -upgrade
• C. terraform refresh
• D. Upgrade your version of Terraform

Answer: (A)

Upgrading provider versions for an existing project is handled during initialization. Running the init command with the -upgrade flag reinitializes the working directory and fetches provider plugins, upgrading them to newer versions that still satisfy the version constraints declared in your configuration. This is exactly how you bring in the new provider versions without changing the Terraform binary itself. The other options don’t accomplish this: applying changes doesn’t modify provider versions, refreshing updates state from real resources but not provider plugins, and upgrading the Terraform binary itself is done outside of Terraform, not with a Terraform subcommand.
