I have an original Xserve G4 1GHz running Panther Server, and I am wondering if anyone knows if it is possible to upgrade to Tiger client without doing a fresh install? I know the risks involved and all of that stuff, and I do have a full backup of the installation. Though Panther Server is installed, the server isn't actually being used as a "mac server" in the sense that its not a file server or a web server or anything like that. What it is doing is hosting a very expensive proprietary newspaper subscription management software (of which my company no longer has the original installation files for). And the company I work for is so small that there are never more than 10 connections to the xserve anyway.
