Root Cause

The saved plan file was modified or regenerated after creation, causing a checksum mismatch when applying.

Workarounds

  1. 90% success Regenerate the plan with the same configuration and apply immediately: 'terraform plan -out=plan.tfplan && terraform apply plan.tfplan'. 
    Regenerate the plan with the same configuration and apply immediately: 'terraform plan -out=plan.tfplan && terraform apply plan.tfplan'.
  2. 95% success Use 'terraform apply' directly without a saved plan file to avoid the size limit issue.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Plan files are binary and checksummed; any manual edit will corrupt the file and cause a different error.

  2. 80% fail

    Terraform does not support incremental plans; each plan is a full snapshot, and splitting does not reduce total size.

  3. 30% fail

    While this works, it bypasses the plan review process and may apply unintended changes.
