"Migrating all our systems to a single technology platform is not a viable proposition, both in terms of the costs and the technical feasibility," said the bank's deputy head of IT, Lawrie Houghton.
Using the Changeman DS and Teamtrack applications from Serena Software, C Hoare will be able to continue using applications that operate in both Windows 2000 and Unix environments.
The Teamtrack software is web-based application, which means it is comparatively simple to update and requires no intervention on the bank's desktop PCs.
UKfinancial services companies often have platforms that are at least 20 years old and, in some cases, they were implemented by employees who left the organisation many years ago. The legacy systems have been adapted to accommodate new processes and the documentation is not well maintained.
"The reality of the situation is that banks often do not have the people who understand those applications," said Ian Forsythe, UK manager at Serena Software.
Serena Software has also implemented its change management applications for other major banks, such as Spanish giant Banco Santander, which is acquiring Abbey, and UBS.
