Hey Michael! It makes perfect sense to me that Terragrunt would be able to handle this as a simple macro-type functionality. Build a bootstrap, migrate the state file, then update the terragrunt/terraform config.
But I don’t see any functionality in the source that’d do it.
Terragrunt is a thin wrapper for Terraform that provides extra tools for working with multiple Terraform modules. …
Have you done this before? If so, that’s awesome! The documentation should be updated to include it. Please let me know! :)
