Abstract: The current operating system on the primary computer system continues to run, i.e. the computer system on which the operating system is to be changed. A second computer or surrogate computer system with the new operating system to eventually be installed in said first computer system to replace the current operating system. The root volume group of stored data from said first or primary computer system is copied to a computer readable/writable medium external to this first computer system and this root volume group is installed from the computer readable/writable medium into the surrogate or second computer system. This second computer system is run with said root volume group of data to thereby update said root volume group. Now, the upgraded root volume group, including the new operating system, is copied back from the surrogate computer system and reinstalled into said first computer system.

Abstract: Recording the history of the sequential development of each of the plurality of binary files forming the program by developing an initial version of a binary file, then developing a sequential plurality of subsequent changed versions of said binary file, assigning an identifier to each of the subsequent versions of the binary file and storing all of said identified versions of said binary file. The binary file identifiers are preferably binary identifiers, especially bar code identifiers. The assigning of a binary identifier to a version of a binary file is responsive to the completion of said version of said binary file and, preferably, is, thus, automatically responsive.
