Migration Type

There are differences between Terraform OSS / CE / Core migrations and Terraform Enterprise & Terraform Cloud Migrations. Accordingly this Readme has been split between two pages tfe migration and ce migration

tfm in a Pipeline

tfm can be used in a pipeline to automate migrations. There are a few considerations when using tfm in this manner.

• For source and destination credentials use environment variables from the pipeline's secrete manager or other secure means. Don't embed these credentials in tfm configuration files
• Several tfm commands require confirmation before proceeding, which are listed below. To override these in a pipeline, add the --autoapprove flag.
  • copy workspaces Only when all workspaces are going to be migrated due to no workspace list, or map defined.
  • copy workspaces --state --last
  • delete workspace
  • delete workspaces-vcs
  • nuke

Architectural Decisions Record (ADR)

An architecture decision record (ADR) is a document that captures an important architecture decision made along with its context and consequences.

This project will store ADRs in docs/ADR as a historical record.
