Help Center
If your source system had a custom URL for the PTC FlexPLM Help Center, you must update your properties to reflect changes that are new to PTC FlexPLM 11.0 M030.
If modified or overridden, the previous property windchill.onlineHelpCenter.urlContext in custom.lcs.properties needs to be set for wt.properties by adding a new entry to site.xconf using the property wt.fhc.url. Run the xconfmanager tool with the propagate flag (-p) to update wt.properties.
