### ProSBC Replacement

#### Backup your system configuration

If this is a 1+1 system, before proceeding with the procedure, make a backup of your configuration. Please follow this link: [Backup procedure](/maintenance-and-troubleshooting/maintenance-guide/troubleshooting-toolpack.md)\
Note: The database backup should be stored in a safe place

#### Setup a new ProSBC

Install a ProSBC using one of the following methods: ProSBC Installation\
If the same product key is used, it needs to be reset - please contact [TelcoBridges TB Support](mailto:support@telcobridges.com)<br>

### Replacement of a standalone ProSBC

Go through the initial configuration and select "This unit is deployed as a stand-alone unit"\
If the configuration database is available, restore it on the system: [Restoring Database Procedure for v2.8 and up](/maintenance-and-troubleshooting/maintenance-guide/restoring-a-database.md)\
Otherwise you will need to reconfigure the system: ProSBC Configuration<br>

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/maintenance-and-troubleshooting/maintenance-guide.md?ask=<question>&goal=<endgoal>
```

`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.
