W2K3 hardly represents the first migration for eNom, although it's surely been the fastest. Before joining the ranks of Microsoft shops, eNom used Unix-based Web servers and an Oracle database, along with a DNS server running Red Hat Linux.
eNom stepped from the Unix-and-Oracle platform to SQL Server 7 in 1997 and then to W2K Server with SQL 2000 three years later.
Beaver cites several differences between eNom's migrations to W2K, and later to W2K3. "We were able to do this year's migration in about a week and the final cutover in less than an hour," he maintains. "This time around, we already had a ready cluster. Also, unlike in the W2K migration, we were moving to new and separate hardware. We came from Compaq L740 servers, and went to DL580s."
