Howdy, MrAnnex. I work for GoDaddy. First, off -- welcome! :-)
If you're moving to Managed WordPress, there's an automatic migration tool that should pull everything over. The primary place where I've seen issues is if your installation on hostmds is using any duplicative plugins (e.g. caching, etc.). They're listed here, if you want to check. I'll subscribe to this thread, so lemme know if you see any issues!
