GeoDin® update The GeoDin® setup detects if older versions of GeoDin® (GeoDin® 9.6 and GeoDin® 10) were installed using previous setups in the standard way. In this case, the setup offers an update option that also retains the existing system configuration during the update process. The update process is not supported or guaranteed for older versions of GeoDin® or for GeoDin® that was not installed using the regular setup. In such cases, please contact so that we can prepare an offer for you. ![GeoDin update](/files/x8rzWg1wWlKTbwD1Jw6t) Alternatively, you can also update within GeoDin by navigating to **System Configuration > Update GeoDin**, if you do not receive an automated update prompt.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.geodin.com/administration/updating-and-upgrading/upgrade-paths.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
