Is it possible to migrate from RHEL to CentOS on server with existing install of cPanel?

We have cPanel currently running on Red Hat Enterprise Linux Server release 5.8 (Tikanga). Due to a change in licensing we are being forced to move to CentOS. We know it's possible to change from RHEL to CentOS on a server, but is it possible to do on a server that is running cPanel:
REDHAT Enterprise 5.8 x86_64 standard – -- WHM 11.40.1 (build 9)

Thanks.

Changing the entire operating system on an existing server is not something that cPanel supports, and generally it is a bad idea. Even moving from CentOS 5 to CentOS 6 really needs a fresh install instead of trying to upgrade "in place", so it is difficult to imagine how changing from Red Hat to CentOS on a running server would work well.

Though it is true that CentOS is largely RHEL with different branding, the change would still involve changing such a huge number of RPM packages, that it is not something we can support. It would be best to commission a new CentOS server with cPanel, transfer your accounts using the tools we provide, and decommission the Red Hat cPanel server.

Many thanks for the response. I fully agree with your response, and find it a bit of a shame that our current company claims this type of upgrade is quite feasible. We'll investigate acquiring a new server for this task.
