Upgrade to Pro Version

I’ve received a 50% off opportunity to upgrade to the Pro version of eM Client. At the present time I use only two email accounts, and almost all of my support questions have been answered here, so I don’t have a strong need to upgrade. However, I may still do so. If I do, is a migration of my existing data required or is it as simple as installing the Pro version?

There is alot of extra features apart from unlimited accounts in the Pro version.

(See eM Client Pro extra Features on the Pricing page).

When you buy the Pro version, you just change your “Activation Key” and everything stays intact.
