#### Other migrations

If you see errors like `rendered manifests contain a resource that already exists` during installation, you may need to forcibly take ownership.

The script below can handle this for you. Replace `RELEASE` and `NAMESPACE` with the name and namespace of the release:

```console
KINDS=(service deployment)
RELEASE=istio-ingressgateway
NAMESPACE=istio-system

ifeq ($(BUILD_WITH_CONTAINER),1)

# An export free of arguments in a Makefile places all variables in the Makefile into the
# environment. This is needed to allow overrides from Makefile.overrides.mk.

%:
