Create an isolated trial with a documented recovery point and one execution owner.
Supporting detail
- Record exact CLI, provider and module versions.
- Protect a state backup as sensitive data and prove you can restore it.
- Compare plans and investigate unexpected replacements or deletions.
- Validate CI approvals and prevent old and new systems from writing concurrently.
What to decide after the trial
Document accepted differences and any retained hosted-service dependency.Read more
Include the time to maintain providers, review upgrades and handle incidents in the operating budget. IGEARS can assess the Terraform-to-OpenTofu boundary and prepare a migration rehearsal with explicit acceptance and rollback criteria.
