# Downgrade Nightscout

</br>

There is usually no good reason to downgrade Nightscout unless being instructed to do so.

First try to deploy another version if available: see [Deploy another version](/update/dev_branch).

If you use Heroku and you want to return to the previous version, see [Roll back Heroku](/troubleshoot/heroku.md#roll-back-heroku).

## Deploy an old release

</br>

**Azure with Docker** (not using GitHub) use [this method](/update/dev_branch).

</br>

**Experienced users only - not recommended**

Deploying an archived release of Nightscout is complex and involves using Git on your computer (You need to [install git](https://git-scm.com/downloads) if you're using a Windows computer).

Before starting you need to have the project `nightscout/cgm-remote-monitor` forked in your GitHub repository, with not only the master fork copied (look out for the check box!). It is recommended to [redeploy](/update/redeploy) paying attention to this step.

Clone it locally (navigate to the folder where you'll want it saved locally before cloning). Replace YOUR-USERNAME by your GitHub user name.

`git clone https://github.com/YOUR-USERNAME/cgm-remote-monitor`

First identify the commit matching the release you want to use, look into the [released versions](https://github.com/nightscout/cgm-remote-monitor/releases).

Then create a branch out of this commit (replace BRANCH by the branch name you want and indicate the COMMIT matching the one you need, in the case above b627d31):

`git checkout -b BRANCH COMMIT`

Push this new branch to your repository

`git push --set-upstream origin BRANCH`

</br>

You can now [deploy](/update/dev_branch.md#step-2-deploy) it in your web app, selecting it in the drop down menu.
