If you modified any Velocity templates for user-facing windows, to preserve the customized user experience, some of your custom changes must be migrated manually to the new installation manually for each server node.
The templates are located in the <pf_install>/pingfederate/server/default/conf/template directory.
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>.
Supporting CSS and image file names changed as of PingFederate 7.0. For each modified
HTML template copied, add .1 to the base name for each CSS file
referenced in the header, such as <link rel="..."
href="assets/css/window.1.css"/>.
Add .1 to any references in the copied templates to the installed
image files contained in the assets/images directory, such as
<img src="assets/images/green_check.1.png"/>.
