@viniciusdc this looks good to me. Can you verify that you can redeploy (without doing destroy in between) and delete the stages directory. I want to check that the terraform import is working as expected.

Hi @costrouc, testing results:

• Just simple redeploying worked fine, even updating the qhub-config lead to no issue
• Deleting the stages/ dir and redeplogin lead to the folowing error:

[terraform]: │ Error: A resource with the ID "/subscriptions/********/resourceGroups/qhubstages-dev-state" already exists - to be 
[terraform]: | managed via Terraform this resource needs to be imported into the State. Please see the resource documentation
[terraform]: | for "azurerm_resource_group" for more information.

Ok, so I forgot to add the correct resource names for the state blocks, so the generated import-config didn't match what was previously submitted.

Awesome thanks for this quick worker @viniciusdc 😄
