### Vista diagram links

Because the Query Server name includes the computer name, which has changed from the old system to the new, any Vista diagrams that use Custom Query Server links must be updated. Updating the Custom Query Server links can be done manually by opening the diagram and changing the Query Server link of the diagram background.

If inheritance is used in the Vista diagram, then only the top most diagram needs to have its Query Server link updated. The update filters down into any linked diagrams.

However, for a large number of diagrams, use a search and replace tool that can find the Query Server strings in the diagram files and update them to the new server name.

Note: Search for the Query Server string settings where the `use_parent` link option is set to `0`. There are many server references in each Vista diagram that have a `use_parent` link set to `1`; you can ignore these.

The same is true for any links in the diagrams (for example, a numeric value) to the VIP(s) that were migrated from the old system to the new. The name of the VIP might reference the computer name, and if this name has changed, then the links to the VIPs must be updated.
