Summary

This pull request (PR) adds instructions for upgrading a BloodHound Enterprise on-premises instance as described in DOCS-26 (Aha!).

I tested these instructions by attempting to upgrade a v9.4.0 instance to v9.6.0. I wasn't able to complete the process because of a database error. v9.6.0 requires PG18, but my v9.4.0 instance (bundled with embedded cluster) is running PG16.

It doesn't appear that we need to document the PG upgrade scenario at this time. However, it might be prudent to hold off on publishing these docs until I can test v9.6.0 against a future version where there is no PG compatibility issue.

Staging

We no longer have access to staging builds on Mintlify 😒

But you can build the site locally to preview the changes.

Walkthrough

Added an On-premises BloodHound Enterprise upgrade page. The guide covers embedded-cluster prerequisites, web-based upgrade execution, validation, support bundles, troubleshooting, and retries. The page was added to the documentation navigation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 65967

The upgrade instructions select headless mode but then direct administrators to use the interactive Upgrade Wizard, which may make the documented on-premises upgrade process unusable. This should be corrected or explicitly accepted before merging.

Poem

I’m a rabbit with a guide in my paws,
Checking each cluster for errors and flaws.
Upgrade, then validate the pods in a row,
Gather support bundles when troubles show.
Retry with care, and the new page will glow.

<Step title="Check the installed version">
Print the embedded cluster and BloodHound Enterprise application versions. Save the output so you can compare it with the post-upgrade version.

```bash
sudo ./bloodhound-enterprise version
```

Expected output looks similar to the following:

```text
Embedded Cluster: 3.0.0-alpha-9 (commit 181fed8, built 2026-01-28_18:35:09)
Application: bloodhound-enterprise 0.0.1 (revision 1, channel sequence 9)
```
</Step>

Clarify the version-comparison example.

This step tells the reader to save the pre-upgrade version output to compare with the post-upgrade version. The example output here shows Application: bloodhound-enterprise 0.0.1 (revision 1, channel sequence 9). Compare this to the post-upgrade example at Line 279, which shows Application: bloodhound-enterprise 0.0.1 (revision 2, channel sequence 9). The Application version string is identical in both examples; only revision changes.

Since the entire purpose of this comparison is to confirm the upgrade succeeded, a reader following the example literally may conclude that only the revision value is expected to change, not the version itself, or may mistake an unchanged version for a failed upgrade. Update one of the two example outputs to show a differing application version, so the example clearly demonstrates a successful version change.

Acknowledged. See my comment on line 197. Will keep this open as a reminder to update the "after" version command output.

@jeff-matthews, acknowledged. Keeping the thread open is appropriate until the post-upgrade version output shows a different Application version.

Remove --headless from the web-based upgrade command.

--headless runs the Embedded Cluster upgrade without the interactive installer UI. The following steps require the Upgrade Wizard, so this command does not match the documented workflow. Remove the flag or document the headless workflow separately.
