## What it is
tfmigrate is a CLI tool for safely migrating Terraform and OpenTofu state files in a GitOps-friendly, declarative way. It lets you write state mv/rm/import operations as HCL migration files, dry-run them, and track applied migration history.

## Use cases
- rename or move terraform resources in state without manual terraform state mv commands
- split or merge terraform state files when refactoring a monorepo
- import existing infrastructure into terraform state declaratively
- dry-run state migrations and verify terraform plan shows no changes
- track and apply unapplied state migrations in sequence in CI
- replace state providers across a terraform codebase

## When to choose
- you practice GitOps and want state changes committed as reviewable code
- you need to refactor terraform state across multiple tfstates in a monorepo
- you want safe, simulated state migrations before touching remote state

## When to avoid
- you only need simple one-off state edits and are comfortable with terraform state commands directly
- you use IaC tools other than Terraform or OpenTofu
