Can I upgrade to a multi-user product later?

I have recently purchased a Youmehub single-user product. Can I upgrade to a multi-user product? and how much will it cost?

Customers who have purchased Youmehub (Single-User Mac) or Youmehub (Single-User Win) can upgrade to one of the multi-user products. Your data can be migrated form your single-user data file into your new multi-user data file. You will also receive a discount on your previous purchase cost.
If you wish to upgrade please send us an email requesting an upgrade.
