How to sync/upload local changes after checkout a different branch locally with VCS

Hi I have a simple user case quiry, I'm using remote intepreter, if I have just create a new branch and did some development and uploaded the changes to remote server, and now I checkout to orginal branch, how to also let the deployment files also 'checkout' back to the original branch? do I have to manually upload all files once to ensure all files are changed back?

Thanks and looking forward to your reply!
