Your complete vault is stored in one folder that has the same name as your vault. If you look into your online storage, you’ll find it. Copy that folder to your new destination. Then delete the vault from cryptomator. This will only delete the connection to the vault, not the files. After you have finished copying the folder, add in cryptomator (or in the app) an existing vault, and select the folder at your new destination. Check if everything works fine. If this is the case, you can delete the files in the source destination.

Cryptomator files are just files like any of your other files you may store in your cloud storage. If you have problems with up-/donwloading files with the google drive sync app, this is an issue of gDrive. I never had such problems.
