As we've mentioned in Chapter 7, Taking It to the Enterprise:

"Part of your enterprise roadmap must eventually include upgrading to (ultimately) the professional version of IBM Watson. Simply put, you start with the free version for your test drive, upgrade to the personal version to develop your personal expertise, and when you are ready, you go pro (with the professional version)."

To that end, let's now go over the process of upgrading to Watson Professional. Once you have logged in to Watson, you can click on your name and select either My account or Upgrade, as shown here:

I recommend that you click on My account. If you click on My account, you have the opportunity to review the space you are currently consuming and your data limitations and, if you have one, enter a promotion code (promotion codes are codes provided by IBM or their partners for limited free or discounted use of Watson). If you are working for an IBM partner, your employer may be able to provide you with such a promotion code:

Once you click on the Upgrade account button (circled in the preceding screenshot), you enter Cloud Shop, where you can click on Purchase as shown in the following screenshot:

From there you can scroll down to where you see the Professional edition selection shown, and click on Configure and buy:

Once you click on Configure and buy, you have the option to change the number of users authorized to use your subscription to Watson, as well as add more disk space, before you continue to the checkout.

At the checkout (similar to any online shopping cart), you have to select a payment method, fill in the required information, and submit your order. That's all there is to it!
