The decision to rollout Vista will enable the company to exploit the improved security that the operating system offers and added benefits such a significant step toward the goal of a remotely managed desktop computing environment.
âMigrating legacy applications to a new operating system is always a challenge, especially in a large company where the range of such applications is usually wide,â said Mark Briston, the Vista project manager for Old Mutual. âWe are dealing with a core set of 250 applications including off the shelf and bespoke varieties so our original compatibility testing timeframe was planned to be around nine months.â
Briston continued, âFor various reasons, the nine-month testing period had to be shortened significantly and the project needed to find tools which would save time, reduce testing effort and not require extensive training of project staff. We discovered AOK from ChangeBASE and after a day with their consultants, our project staff were able the use AOK confidently and accurately.â
Overnight, ChangeBASE developed a utility for the conversion of WSE files to MSI format. Within two days three core legacy applications had been tested and remediation started on them. The project team were confident enough after three days to take over the toolset and continue the testing on their own,â Briston adds.
âWithin a month all 250 applications had been tested, resulting in a major time and cost saving for the project and allowing applications needing remediation to be identified quickly and remediated much earlier that originally expected,â comments John Tate, CEO, ChangeBASE. âAs a result of the success of this project, the two organisations are currently collaborating on a further tool and designing a set of best practices for Old Mutualâs in-house developers.â
