If you have a current license with Sage the answer is yes, but you'll want to involve your Sage Partner / reseller for some detailed / hands-on assistance.  Upgrading Sage / MAS is not really a DIY type activity, especially from such an old version.

(Our in-house checklist has over a hundred points, many of which are not in Sage documentation... things we've learned as "best practices" over the years).

As mentioned by rclowe and JohnS, there is a technical limitation on upgrades from older versions, meaning you have to be on at least v4.5.8 for a one step upgrade... otherwise you have to do an extra migration / data conversion in the middle of the process.  Again, your Sage Partner will know all about this and can guide you in the upgrade process.
