Manually building the Validation Server from the VIP EG console or using the export/import feature should be used whenever creating a new validation server. If those methods fail or if the shared secret is unknown, these instructions can be used to manually copy a Validation Server from another VIP Enterprise Gateway to another and manually create the Windows service.
The IMPORT function transforms the settings to match the target VIP EG. This manual method does not do that and requires the source and destination VIP EG server be the same major version. For example, 9.8.x to 9.8.x.
