Step 1: Install OpenTofu

OpenTofu CLI is a drop-in replacement for terraform CLI.

brew install opentofu  # or: curl -s https://packagecloud.io/install/repositories/opentofu/tofu/script.deb.sh | sudo bash
Step 2: Replace CLI calls

Replace `terraform` with `tofu` in all scripts, CI/CD pipelines, and Makefiles.

sed -i 's/terraform/tofu/g' Makefile .github/workflows/*.yml
Step 3: Update state backend (optional)

Existing state files are compatible. No migration needed. OpenTofu reads Terraform state format.

Step 4: Check provider compatibility

Most providers work. Verify your registry source — use registry.opentofu.org or keep registry.terraform.io for now.
