  1. Is there a way to test our integrations prior to a maintenance in order to ensure they are set up correctly?

    1. If you would like to test integrations, you may do so by choosing to participate in a site switching exercise. For more information, see the Site Switching - Customer FAQ article.

  1. Do I need to make any changes to my Sender Policy Framework (SPF) records?

    1. We recommend enabling the “Enable compliance with standard email security mechanisms” option, but in the unlikely case that you have specific Salesforce IP addresses listed in your SPF, you will need to update them to include the ranges for your new data center location or include the SPF records that cover all IP ranges. For more information, please see our Sender Policy Framework (SPF) and Salesforce SPF Record article.

    1. Please see the Required Domains article.
