Some data does not upgrade. For example, if you have selected a Home Page in the Client. Others not migrated to the new version:
• Client home page selection -- The client home page is the About box by default in the new installation.
• Event Templates -- Since the structure of events changed completely since 5.3.8, any customized event templates are not preserved in an upgrade. You can, however, export the event templates to XML and read the XML to remind yourself of the customization to be recreated in 6.0.2+.
• Change policies
• Syslog messages migrate to the new version with some caveats. The original severity and facility are lost. All syslog messages are converted to historical events as opposed to open or closed alarms. Variable bindings will only contain message text from any event (original message text with some prefix).
