ABSTRACT

The end of the operational life of a computer system needs to be managed. This chapter discusses the implications of phasing out computer systems as a result of site closures, divestments, and acquisitions. Various system-management and record-management options are discussed. Key steps for all these situations include

• Retirement of the legacy system • Archiving of electronic records and documentation • Migration to a replacement system where appropriate • Final decommissioning

SITE CLOSURES, DIVESTMENTS AND ACQUISITIONS

Disentangling computer systems as part of site closures, divestments, and acquisitions is becoming more complex as systems become more integrated. A decade ago systems could be switched off with little consequence. Nowadays record retention, data integrity, and security access requirements for GxP information mean the management of computer systems needs careful planning.
