## TL;DR
## Introduction
ThirdPartyResource is replaced by CustomResource and will be entirely deprecated in Kubernetes 1.8.
Since Fission stores state in TPR, we need to migrate from TPRs to CRDs for future Kubernetes
release.
Kubernetes ThirdPartyResources ("TPR") are replaced by
CustomResourceDefinitions ("CRD"). TPRs have been deprecated and are
removed in Kubernetes 1.8.
Below we describe a tool for migrating your TPRs to CRDs.
Since Fission stores state in TPRs, we need to migrate this state from
TPRs to CRDs while upgrading.
Follow the instructions below if you're upgrading a Fission 0.2.1 or
0.3.0 cluster to 0.4. If you're using a pre-0.2 Fission cluster, use
the [upgrade guide from 0.1 to 0.2]() and then upgrade to 0.4.0.
## How to Upgrade
1. Get the v0.4-rc CLI
1. Get the 0.4.0-rc CLI
2. Get the Fission state from v0.3 install
3. Upgrade to Fission v0.4.0-rc
3. Upgrade to Fission 0.4.0-rc
4. Upgrade Kubernetes cluster version to 1.7.x or higher
5. Remove all TPR definition (for Kubernetes 1.7.x)
6. Restore Fission state into CRDs
