Can i download my server?

So, i made this thread to ask if there is any possiblity for me to download my server because i'm changing my host and i have my server here made with my friend, i'm his dev and that's why we want to change our host, we have a forum and everything but we want a store and a few other things we can't add on aternos!

I meant my server files, everthing, not to upload anything, to export!
