Hey everyone,

I’m in the process of updating our Metaflow AWS stack with a new version of the Terraform template (previously used <http://The%20root%20module%20does%20not%20declare%20a%20variable%20named%20"aws_region"%20but%20a%20value%20was%20found%20in%20file%20"prod.tfvars".%20To%20use%20this%20value,%20add%20a%20"variable"%20block%20to%20the%20configuration.%20%20Using%20a%20variables%20file%20to%20set%20an%20undeclared%20variable%20is%20deprecated%20and%20will%20become%20an%20error%20in%20a%20future%20release.%20If%20you%20wish%20to%20provide%20certain%20"global"%20settings%20to%20all%20configurations%20in%20your%20organization,%20use%20TF_VAR_...%20environment%20variables%20to%20set%20these%20instead.%20%20%20Warning:%20Argument%20is%20deprecated|this one>, now upgrading to <https://github.com/outerbounds/terraform-aws-metaflow/tree/47cff650988960c67fbd805b5f184cc6ba988a6b|this>).

I am worried about losing all the results and metadata of Flows executions that were run in the previous setup. I assume that I need to make sure that in `terraform plan` the `METAFLOW_DATASTORE_SYSROOT_S3` and `METAFLOW_DATATOOLS_S3ROOT` have to point to the same buckets as before. But I am unsure about the Metadata service? How can I make sure this data is preserved after the update?

Thanks a lot for any help
