alright, I'm going to mess with the server stuff tomorrow. It's going to be a long ride to say the least
Not sure how I want to go about this though. I can either backup all the VMs, download them to my PC, fully wipe the server and reconfigure it, and reupload the VMs and import them OR I could edit all the configs on this current install of Proxmox VE, change my user account to a new one, and remove the old version of Lets Encrypt that I'm using, and set it up for the new domain.
*sigh*
