How to Change Upstream in Pantheon?

Changing the upstream branch in Pantheon is a crucial step in managing your website’s codebase. In this article, we will guide you through the process of changing upstream in Pantheon, covering the basics, best practices, and potential issues.

What is Upstream in Pantheon?

Before we dive into the process, let’s understand what upstream means in Pantheon. In simple terms, upstream refers to the original or main branch of your website’s codebase, usually the default branch (e.g., master). This branch serves as the central repository for your code, and changes made to it will be reflected across all sites that depend on it.

Why Change Upstream?

You might need to change upstream in Pantheon for several reasons:

• Reorganizing your codebase: You may want to restructure your codebase or create a new upstream branch to better manage your site’s complexity.
• Merging changes: When you make changes to your code, you might need to update the upstream branch to reflect those changes.
• Switching between branches: You might want to switch between different upstream branches depending on the specific requirements of your site.

Changing Upstream in Pantheon

Changing upstream in Pantheon involves updating the upstream branch reference for your site. Here’s a step-by-step guide:

Using the Git Command

The most straightforward way to change upstream is by using the Git command-line interface. You can do this by running the following command:

git push -u origin <new-upstream-branch-name>

Replace <new-upstream-branch-name> with the name of the new upstream branch you want to switch to.

Using the Pantheon Dashboard

Alternatively, you can change upstream using the Pantheon dashboard. To do this:

1. Log in to your Pantheon account and navigate to the dashboard.
2. Click on the "Settings" icon (gear icon) next to your site’s name.
3. Click on "Code" and then "Upstream" in the navigation menu.
4. Click on the "Change Upstream" button.
5. Enter the name of the new upstream branch you want to switch to.

Best Practices

When changing upstream, keep the following best practices in mind:

• Use the correct branch name: Ensure you enter the correct branch name to avoid errors or conflicts.
• Test your changes: Before committing changes, test your site to ensure it functions correctly with the new upstream branch.
• Communicate with your team: If you’re working with a team, notify them of the change and ensure everyone is on the same page.
