If you modified the email notification templates prior to PingFederate 9.2, manually migrate your custom changes to the new HTML-based templates for each server node.
The plain text templates (message-template-*.txt) are located in <pf_install>/pingfederate/server/default/conf in the source installation. The new HTML-based templates are located in <pf_install>/pingfederate/server/default/conf/template/mail-notifications with the same file naming convention but an .html file extension.
As of PingFederate 11.0, the upgrade utility tool migrates your modified Velocity HTML
templates to the new installation. The default templates in the new installation that
correspond to the modified templates are renamed with the following format:
<template_name>-default-<PF-version>.<ext>
.
