How to Prepare for a Web Agent Upgrade
You can prepare for upgrading a Web Agent using the following process:
1. Review the upgrade process in the SiteMinder Upgrade Guide.
2. Back up any customized files on your web server.
3. Review the Password Services and Form Template changes that occur during
the upgrade.
4. Review the changes to the various Web Agent configuration files that occur
when you run the Web Agent Configuration wizard after an upgrade.
5. Set the LD_PRELOAD variable to avoid conflicts with existing Web Agents.
6. Replace existing read-only files during the upgrade (if prompted).
Review the Upgrade Procedure
Before upgrading a Web Agent, you should review the upgrade process in the
SiteMinder Upgrade Guide. This guide contains important overview information
as well as critical tasks that you should complete before upgrading a Web Agent.
Note: If you have upgraded the web server itself since you last installed the Web
Agent, the Agent upgrade may not work. The upgrade is ensured only if the web
server version has remained the same since the last Web Agent installation.
Back Up Customized Files
Customized files may be overwritten by the upgrade. Back up configured files,
such as Agent and Host configuration files before upgrading.
