OS X Server 10.1 Server Admin install glitch

There is a problem with installing a later version of Server Admin atop a previous version. Damon Sorrentino writes: "We're using Mac OS X Server 10.1 and all of are clients are using at least OS X 10.0. Consequently we needed to upgrade Server Admin to a compatible version. Repeated attempts to install it on a< variety of clients gave the exact same error: unable to install, please try again. Apple was able to duplicate the problem and provided this solution. The later version of Server Admin will not install over the current version. We were directed to /Hard Drive/Library/Receipts and told to remove and delete the existing Mac_OS_Server_Admin.pkg and MacintoshManagerAdmin.pkg. Subsequently Server Admin and Macintosh Manager installed flawlessly. I was told by Apple to expect a Knowledgebase article on this soon."
