+# Migrating Existing Envbox Templates
+
+Due to the [deprecation and removal of legacy parameters](https://coder.com/docs/v2/latest/templates/parameters#legacy)
+it may be necessary to migrate existing envbox templates on newer versions of
+Coder. Consult the [migration](https://coder.com/docs/v2/latest/templates/parameters#migration)
+documentation for details on how to do so.
+
+To supply values to existing existing Terraform variables you can specify the
+`--variable` flag. For example
+
+```bash
+coder templates create envbox --variable namespace="mynamespace" --variable max_cpus=2 --variable min_cpus=1 --variable max_memory=4 --variable min_memory=1
+```
+
