I recently upgraded our lab from 2.6.0 to 2.7.7. I am not sure about your upgrade path, but during my upgrade, I tried to directly upgrade to 2.7.7 using 2.7.7 packages but it failed and complained missing elements of 2.6.2 and some
<b>other libraries</b>. So I tried to install packages from 2.6.2 rpm packages and I still got the errors for missing 2.6.1 elements and other libs. So I need to first upgrade to 2.6.1, then to 2.6.2 and then to 2.7.7. Maybe part of your problem is because
of this. From my experience, ISC team did a very good job that the only external dependencies we need is liblog4cplus and maybe there’s another I cannot recall, but I do remember I also needed to upgrade liblog4cplus to newer version as well.

<div>Hey Darren,</div>
<div> Thanks for your reply.</div>
<div><br>
</div>
<div>I have rebuilt my server to a patched RedHat 9.5 VM, created an repo for Kea, which includes the 2.6.2 RPM's for isc-kea-common, isc-kea-ctrl-agent, isc-kea-dhcp4, isc-kea-doc, and isc-kea-hooks.</div>
<div><br>
</div>
<div>When running the install I am getting told that "nothing provides" libboost_system.so.1.66.0 and liblog4cplus-1.2.so.5. I get this error for all four of the app RPM's I am trying to install.
<br>
</div>
<div><br>
</div>
<div>In a short search I was able to install libboost_system via the boost-system RPM, which is 1.75.0-8.el9.
<br>
</div>
<div><br>
</div>
<div>When retrying the install I am getting the same error. Are you specific to the 1.66 so library? <br>
</div>
<div><br>
</div>
<div>Or am I still missing something?</div>
<div><br>
</div>
<div>Thanks,</div>

Hi Scott,<br>
<br>
I suggest you have a look at using the ISC Cloudsmith repository for<br>
install with "yum" or "dnf".<br>
- See here: <a href="https://cloudsmith.io/~isc/repos/kea-2-6/setup/#formats-rpm" rel="noreferrer" target="_blank">
https://cloudsmith.io/~isc/repos/kea-2-6/setup/#formats-rpm</a><br>
- and here: <a href="https://kb.isc.org/docs/isc-kea-packages" rel="noreferrer" target="_blank">
https://kb.isc.org/docs/isc-kea-packages</a><br>
- Please note that it will be unlikely that you can "upgrade" from 2.4<br>
and will rather require a fresh install unless the source of 2.4 was<br>
also Cloudsmith.<br>
Having this repository installed will make it easy for you to update<br>
to new point releases. Additionally, when upgrading beyond 2.6.2 (to<br>
3.0.0, for example), it will be a simple matter of installing the new<br>
repository and executing `dnf upgrade`.<br>
<br>
As far as things to be aware of when upgrading from 2.4 to 2.6, there<br>
are a few sources of information.<br>
- Here: <a href="https://kb.isc.org/docs/changes-to-be-aware-of-when-migrating-to-kea-2-6-0" rel="noreferrer" target="_blank">
https://kb.isc.org/docs/changes-to-be-aware-of-when-migrating-to-kea-2-6-0</a><br>
- and here: <a href="https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.0" rel="noreferrer" target="_blank">
https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.0</a><br>
- and 2.6.1: <a href="https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.1" rel="noreferrer" target="_blank">
https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.1</a><br>
- and finally 2.6.2:<br>
<a href="https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.2" rel="noreferrer" target="_blank">https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.2</a><br>
<br>
As for your question about whether HA will function with one server on<br>
2.4 and one on 2.6, the answer is: it might. 2.6 has a new failover<br>
mode (hub and spoke) and some new messaging that is introduced. The<br>
unknown messages will be ignored by the server that doesn't understand<br>
them (2.4) but this could potentially cause some problems for the<br>
server sending them (2.6). If the 2.6 server is your standby (in a<br>
hot-standby relationship), and no failover events occur, you'll<br>
probably be ok. It is best to not let this situation persist for<br>
long.<br>
<br>
Also note that if you are using database storage at all, Kea will<br>
refuse to start if the database schema is not updated. See here:<br>

Thank you,<br>
