-## Upgrade from terraform 0.12 and keycloak provider 1.x
-
-Please read https://www.terraform.io/upgrade-guides/0-13.html first. For a keycloak project follow the following steps in order:
-
-1. `terraform -v` should print 0.13 and list no keycloak provider
-1. `terraform state replace-provider registry.terraform.io/-/keycloak mrparkers/keycloak`
-1. find all `provider keycloak {...}` blocks in `*.tf` (also in all modules you are including) and delete the `version` line
-1. add the `terraform { required_provides { keycloak = { ...` block mentioned in "Installation" to `terraform.tf` (also in all module directories you are including). Be sure to also always add "source" or else the Terraform looks for "hashicorp/keycloak"!
-1. `terraform 0.13upgrade`
-1. `terraform init`
+If you are using any provider version below v2.0.0, you can also follow the [old instructions for installing third-party plugins](https://www.terraform.io/docs/configuration-0-11/providers.html#third-party-plugins).
