That summary is exactly right—and the impact is important to understand before proceeding. Here’s a complete impact checklist and guidance for what you need to check/update if you change your HCP Terraform Organization name:

Checklist: What to Check When Renaming HCP Terraform Organization

1. Terraform Backend Configurations

• Every Terraform project that uses: backend "remote" { organization = "OldOrgName" ... } must have the organization value updated to the new name.
• If you miss this, terraform init and all backend-related commands will fail.

---

2. TFE Provider Usage

• If you use the Terraform Cloud/Enterprise provider (tfe):
  • Any resources referencing the old org name (e.g., tfe_organization, tfe_workspace, etc.) must be updated.
  • Example: provider "tfe" { organization = "OldOrgName" }

---

3. API Integrations & Automation

• Any custom scripts or tools that:
  • Call the HCP Terraform API directly and reference the org name in URLs or payloads.
  • Use the CLI with the org name as a parameter.
• Search for hardcoded org names in all your repos/scripts.

---

4. External Integrations

• VCS integrations:
  • GitHub/GitLab/Bitbucket connections may need to be reconnected or updated if they are scoped to the org.
• Notification or webhook targets:
  • Any notification channels that are configured for the old org.
• SSO or identity providers:
  • If org name is used in SSO configs (rare, but possible), review and update.

---

5. In-Progress Runs

• You cannot rename the org if there are runs in progress (applies to any workspace).
  • Pause and let all runs complete before renaming.

---

6. User Experience

• All users viewing the old org in their browser:
  • Need to close tabs and re-login/navigate to HCP Terraform after rename.
• Communicate with your team:
  • Send out a note about when the rename is happening and what each user should do.

---

7. Documentation, Wikis, and Dashboards

• Update internal documentation, runbooks, onboarding guides, and any dashboards or internal tools that reference the old org name.

---

8. Other Tools/CI/CD

• Any CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, etc.) that use the old org name in environment variables, scripts, or API calls.

---

Extra Tips:

• Backup configs/scripts before making changes.
• Test in a non-production org if possible.
• Rollout Plan: Make all code/script changes and merge them to main before performing the rename, to minimize downtime/disruption.

Summary Table: Impacts to Check

Area	Impact if Not Updated	How to Update
Terraform backend	Terraform fails to init/apply	Update organization field
tfe provider	Resource/apply failures	Update provider organization value
API/automation scripts	Script errors, API failures	Search/replace org name
VCS/webhooks/SSO	Integration disconnects	Review & update integration settings
User browser sessions	Errors, stale sessions	Instruct users to refresh
Docs, onboarding, CI/CD	Confusion, pipeline failures	Update all references

If you want, I can provide a Bash/Python script to help you search for old org name usage across your codebase. Just ask!
