Working with Computacenter, the firm has migrated Lotus, Novell and Microsoft e-mail servers onto Exchange 2003 and is embarking on a project to upgrade its NT4 servers to Windows 2003. Peter Dewar-Haggart, IT infrastructure programme manager at VT Group, said some applications would still need NT4. "Some legacy shipbuilding applications only run on NT4 and there is no upgrade path," he said.
To keep such applications running, Dewar-Haggart is planning to use the VMWare virtualisation software. This will allow the applications to benefit from modern hardware, he said.
