# Roadmap

In our planning discussions we identified broad three areas of work:

- Feature parity with Flux v1 in read-only mode
- Feature parity with the image-update functionality in Flux v1
- Feature parity with Helm Operator v1

All of the above will constitute "Flux v2".

## The road to Flux v2

### Flux read-only feature parity

[= 100% "100%"]

This would be the first stepping stone: we want Flux v2 to be on-par with today's Flux in
[read-only mode](https://github.com/fluxcd/flux/blob/master/docs/faq.md#can-i-run-flux-with-readonly-git-access)
and [FluxCloud](https://github.com/justinbarrick/fluxcloud) notifications.

Goals

-  <span class="check-bullet">:material-check-bold:</span> [Offer a migration guide for those that are using Flux in read-only mode to synchronize plain manifests](https://toolkit.fluxcd.io/guides/flux-v1-migration/)
-  <span class="check-bullet">:material-check-bold:</span> [Offer a migration guide for those that are using Flux in read-only mode to synchronize Kustomize overlays](https://toolkit.fluxcd.io/guides/flux-v1-migration/)
-  <span class="check-bullet">:material-check-bold:</span> [Offer a dedicated component for forwarding events to external messaging platforms](https://toolkit.fluxcd.io/guides/notifications/)

Non-Goals

-  Migrate users that are using Flux to run custom scripts with `flux.yaml`
-  Automate the migration of `flux.yaml` kustomize users

Goals
