As of CloudBlue Commerce 21.0, the Hosted Exchange module is no longer supported, meaning that those who have the Hosted Exchange module on their installations must prepare these installations for the upgrade.

To prepare your CloudBlue Commerce installation for the upgrade, you must complete the following steps:

  1. Remove the Hosted Exchange module as described in this KB article.
  2. Remove the Windows Hosting Infrastructure components, as described in this KB article.

Important: The upgrade will be stopped until you prepare your installation.
