Learn about a primary PI AF server upgrade

The procedures in this section guide you through upgrading the primary PI AF server in a collective. The first step is to make a full backup of the PI AF (PIFD) database.

Note: Following an upgrade to PI AF 2.7 or later, the first time a client connects to the upgraded PI AF server, some final upgrade operations occur that may cause a brief period of slow performance. We recommend that you force the occurrence of these operations by connecting to your upgraded PI AF server with AF Collective Manager (or PI System Explorer) immediately after the upgrade program completes.
