A Cost-Effective Approach for Migrating Enterprise Electronic Mail Systems
Emmanuel Omojokun, Adeyemi A Adekoya, Ephrem Eyob
Electronic mail (E-mail) is one of the most utilized application
software systems in modern-day organizations. The major
messaging application programs used in the enterprise are IBM
Lotus Notes also known as Domino, Microsoft Exchange
Servers, and Novel GroupWise. For various reasons – such as
high cost of maintenance, undeliverable e-mail issue and loss of
attachments, companies find it necessary to either migrate to
newer versions of their messaging software or to an entirely
different software. In either case, the process must be carefully
planned, well designed and properly implemented to avoid
disaster. In this paper, we present a cost-effective approach for
migrating a particular messaging software. The approach was
implemented and tested for the migration of GroupWise 5.5 to
Exchange Server 2003. We present our success story and
lessons learned from the case. A six-week and one-year post
migration system-audits indicated that the organization derived
several benefits including significant cost savings as a result of
this particular approach. Chief information/technology officers
and e-mail administrators will benefit immensely from the “best
practice” strategy hereby presented. Full Text
