# Common backup and restore limitations and fixes

The following provides guidance on avoiding or resolving common issues encountered during backup and restore.

<details>

<summary>Unable to restore between different versions</summary>

The backup Cortex XSOAR version must be the same **exact** version as the currently installed version. For example, if the backup version is 8.10.0.28, you can restore only to 8.10.0.28.

</details>

<details>

<summary>Restore fails when the new cluster has different configurations and hardware specifications from the backup cluster</summary>

Ensure the new cluster has the following configurations and hardware specifications:

* The FQDN for the new cluster must be the same as the previous cluster.
* The new cluster must have the same amount of nodes as the previous cluster.
* The new cluster must have the same scale size (CPU, memory, and disk space) as the previous cluster.
* The tenant Account Admin user for the new cluster must have the same password as the tenant Account Admin user in the previous cluster.

### Note

The node IP addresses in the new cluster can differ from the previous one.
{% endhint %}

</details>

<details>

<summary>External storage and backup configurations are not retained when restoring on a new cluster installation</summary>

If you restore on a new cluster installation, you will need to reconfigure the external storage and backup scheduler.

If you restore on the same cluster where the external storage was originally configured and the backup was created, reconfiguration is unnecessary.

# 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 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://cortex-docs.paloaltonetworks.com/cortex-xsoar-8-on-prem/8.10/onboard-cortex-xsoar/back-up-and-restore-cortex-xsoar/common-backup-and-restore-limitations-and-fixes.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.
