# Problemer med opgraderingsprocessen

Retter SQL- og webgrænsefladefejl efter en opgradering af Devolutions Server, som skyldes en forkert version af konsollen, herunder problemer med ugyldigt klient-id.

Efter en opgradering af Devolutions Server udløses fejlmeddelelser som SQLException - Invalid column name i loggene eller fejlmeddelelsen Error: cannot read property 'children' of null i webgrænsefladen for Devolutions Server.

Årsagen til disse fejl er en SQL-database eller webprogramfiler, der ikke er opdateret korrekt, fordi opgraderingen af webprogrammet for Devolutions Server er udført med en ældre Devolutions Server Console.

### Løsning

Kontrollér først, at Devolutions Server Console svarer til versionen af webprogrammet for Devolutions Server.

Hvis versionen af Devolutions Server Console er ældre end versionen af webprogrammet, skal De gå til [downloadsiden](https://server.devolutions.net/home/download) for Devolutions Server for at downloade den rigtige version af Devolutions Server Console og installere den.

Installér derefter webprogrammet for Devolutions Server igen oven på den aktuelle installation med knappen Upgrade Server i ruden Actions. Det installerer alle nødvendige filer korrekt og opdaterer SQL-databasen til den rigtige version.

{% hint style="success" %}
Vi anbefaler på det kraftigste at følge instruktionerne i [Opgradering af Devolutions Server](/server/da/getting-started/installation/devolutions-server-upgrade.md) for at udføre opgraderingen.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/server/da/knowledge-base/troubleshooting-articles/upgrade-process-issues.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
