+# Introduction
+
+This document explains how to upgrade from
+[Clear Containers](https://github.com/clearcontainers) to
+[Kata Containers](https://github.com/kata-containers) and how to upgrade an existing
+Kata Containers system to the latest version.
+
+# Unsupported scenarios
+
+Upgrading a Clear Containers system on the following distributions is **not**
+supported since the installation process for these distributions makes use of
+unpackaged components:
+
+- [CentOS](https://github.com/clearcontainers/runtime/blob/master/docs/centos-installation-guide.md)
+- [BCLinux](https://github.com/clearcontainers/runtime/blob/master/docs/bclinux-installation-guide.md)
+- [RHEL](https://github.com/clearcontainers/runtime/blob/master/docs/rhel-installation-guide.md)
+- [SLES](https://github.com/clearcontainers/runtime/blob/master/docs/sles-installation-guide.md)
+
+Additionally, upgrading
+[Clear Linux](https://github.com/clearcontainers/runtime/blob/master/docs/clearlinux-installation-guide.md)
+is not supported as Kata Containers packages do not yet exist.
+
+# Maintenance Warning
+
+The Clear Containers codebase is no longer being developed. Only new releases
+will be considered for significant bug fixes.
+
+The main development focus is now on Kata Containers. All Clear Containers
+users are encouraged to switch to Kata Containers.
+
+# Upgrade from Clear Containers
+
+Since Kata Containers can co-exist on the same system as Clear Containers, if
+you already have Clear Containers installed, the upgrade process is simply to
+install Kata Containers. However, since Clear Containers is
+[no longer being actively developed](#maintenance-warning),
+you are encouraged to remove Clear Containers from your systems.
+
+## Stop all running Clear Container instances
+
+Assuming a Docker\* system, to stop all currently running Clear Containers:
+
+```
+$ for container in $(sudo docker ps -q); do sudo docker stop $container; done
+```
+
+## Configuration migration
+
+The automatic migration of
+[Clear Containers configuration](https://github.com/clearcontainers/runtime#configuration) to
+[Kata Containers configuration](https://github.com/kata-containers/runtime#configuration) is
+not supported.
+
+If you have made changes to your Clear Containers configuration, you should
+review those changes and decide whether to manually apply those changes to the
+Kata Containers configuration.
+
+> **Note**: This step must be completed before continuing to
+> [remove the Clear Containers packages](#remove-clear-containers-packages) since doing so will
+> *delete the default Clear Containers configuration file from your system*.
+
+## Remove Clear Containers packages
+
+> **Warning**: If you have modified your
+> [Clear Containers configuration](https://github.com/clearcontainers/runtime#configuration),
+> you might want to make a safe copy of the configuration file before removing the
+> packages since doing so will *delete the default configuration file*
+
+### Fedora
+
+```
+$ sudo -E dnf remove cc-runtime\* cc-proxy\* cc-shim\* linux-container clear-containers-image qemu-lite
+$ sudo rm /etc/yum.repos.d/home:clearcontainers:clear-containers-3.repo
+```
+
+### Ubuntu
+
+```
+$ sudo apt-get purge cc-runtime\* cc-proxy\* cc-shim\* linux-container clear-containers-image qemu-lite
+$ sudo rm /etc/apt/sources.list.d/clear-containers.list
+```
+
+## Disable old container manager configuration
+
+Assuming a Docker installation, remove the docker configuration for Clear
+Containers:
+
+```
+$ sudo rm /etc/systemd/system/docker.service.d/clear-containers.conf
+```
+
+## Install Kata Containers
+
+Follow one of the [installation guides](https://github.com/kata-containers/documentation/tree/master/install).
+
+## Create a Kata Container
+
+```
+$ sudo docker run -ti busybox sh
+```
+
+# Upgrade Kata Containers
+
+As shown in the
+[installation instructions](https://github.com/kata-containers/documentation/blob/master/install),
+Kata Containers provide binaries for popular distributions in their native
+packaging formats. This allows Kata Containers to be upgraded using the
+standard package management tools for your distribution.
+
+# Appendices
+
+## Assets
+
+Kata Containers requires additional resources to create a virtual machine
+container. These resources are called
+[Kata Containers assets](https://github.com/kata-containers/documentation/blob/master/architecture.md#assets),
+which comprise a guest kernel and a root filesystem or initrd image. This
+section describes when these components are updated.
+
+Since the official assets are packaged, they are automatically upgraded when
+new package versions are published.
+
+> **Warning**: Note that if you use custom assets (by modifying the
+> [Kata Runtime configuration > file](https://github.com/kata-containers/runtime/#configuration)),
+> it is your responsibility to ensure they are updated as necessary.
+
+### Guest kernel
+
+The `kata-linux-container` package contains a Linux\* kernel based on the
+latest vanilla version of the
+[longterm kernel](https://www.kernel.org/)
+plus a small number of
+[patches](https://github.com/kata-containers/packaging/tree/master/kernel).
+
+The `Longterm` branch is only updated with
+[important bug fixes](https://www.kernel.org/category/releases.html)
+meaning this package is only updated when necessary.
+
+The guest kernel package is updated when a new longterm kernel is released
+and when any patch updates are required.
+
+### Image
+
+The `kata-containers-image` package is updated only when critical updates are
+available for the packages used to create it, such as:
+
+- systemd
+- [Kata Containers Agent](https://github.com/kata-containers/agent)
+
+### Determining asset versions
+
+To see which versions of the assets being used:
+
+```
+$ kata-runtime kata-env
+```
