Changing the base branch of a pull request
After a pull request is opened, you can change the base branch to compare the changes in the pull request against a different branch.
Warning
When you change the base branch of your pull request, some commits may be removed from the timeline. Review comments may also become outdated, as the line of code that the comment referenced may no longer be part of the changes in the pull request.
-
Under your repository name, click Pull requests.
-
In the "Pull Requests" list, click the pull request you'd like to modify.
-
Next to the pull request title, click Edit title .
-
In the base branch drop-down menu, select the base branch you'd like to compare changes against.

Read the information about changing the base branch and click Change base.
Tip
When you open a pull request, GitHub will set the base to the commit that branch references. If the branch is updated in the future, GitHub will not update the base branch's commit.
