Mac OS X Server 10.2: "Cannot install due to Errors" over Mac OS X 10.2.1 (Client)

You must use a workaround to install Mac OS X Server 10.2 over a client (non-server) version of Mac OS X 10.2.1. This is because 10.2 server has some earlier component version numbers than 10.2.1 client.
Symptom

When you try to install Mac OS X Server 10.2, an alert box with this message appears:


Solution

Follow these steps:

You should now be able to start up from CD to install Mac OS X Server 10.2. This will create new receipts based on the packages in Mac OS X Server 10.2.

Note: If at any point you choose to repair permissions, they may be incorrectly set for certain items due to the new receipts. You should verify that global permissions correction is necessary. If, for example, an executable file is only allowed to be used by the root user, but an Admin user also requires the ability to execute the file, you would only need to adjust permission on that item to grant rights to the Admin user.
