Move server to different drive

When I started using Plex I installed the server on the C:/ drive of my laptop. Due to (hard drive) size issues, I would like to move the server to my external drive, aka G:/ (which has 627 GB available for use) but I don’t want to mess up what I already done on my C:/ drive. Is it possible to move the server from drive to drive or do I have to start anew and install Plex on the external drive and get rid of the C:/ drive (server) and then start fresh. Also, are there any limitations/issues with having Plex on an external drive?
