In 0.94, this feature of having multiple stages was a hidden feature as it was still work-in-progress. We did a lot of changes/improvements since then which is available now to use in v1.0.

`pipelines.yaml` is now renamed to `dvc.yaml` and has some file format changes. To redefine a stage, you can use `--force` and it should overwrite. In 1.0, you can remove a stage from the pipeline file using `dvc remove <stage_name>`.

Now, for you to migrate, the easiest thing would be to `dvc run` for all stages and build from there (which should now be `dvc.yaml`), and then later remove `pipelines.yaml`.

If you don’t want to `dvc run`, you can edit manually and then rename `pipelines.yaml` to `dvc.yaml` and `pipelines.lock` to `dvc.lock`. The incompatibilities between 0.94 and 1.0 in `.yaml` file is that, we no longer have `metrics_no_cache`, `outs_persist`, `outs_no_cache` kind of sections in dvc.yaml. So, if you do that you might need to make adjustments similar to the following:

In 0.94:

```auto
stages:
  stage_one:
    cmd: "command"
    outs:
     - foo
    outs_no_cache:
     - bar
    outs_persist:
     - foobar

```

In 1.0:

```auto
stages:
  stage_one:
    cmd: "command"
    ...
    outs:
     - foo
     - bar:
         cache: false
     - foobar:
         persist: true

```
