The council has used AppDNA's AppTitude automated testing tool to analyse 120 of Newham's core applications.
Geoff Connell, chief information office at Newham, said, "We found we had lots of versions of the same software and we were able to target the small minority of applications where there were incompatibility issues."
AppDNA examined the applications' ability to install and run under Windows Vista and suggested fixes to address identified issues to make them Windows Vista ready. Connell said that testing Newham's core applications for Vista compatibility took less than a week for one member of the IT team to complete.
AppDNA indicated that nearly 70% of Newham's applications could be migrated directly to Windows Vista without any compatibility issues. Other incompatible applications like CD-ROM burning software was no longer required, as CD-ROM is now built into Vista. And around 10% of Newham's applications would need remediation work to run under Vista.
"In many cases, Vista security has shut-down backdoors which were being used by these applications," he said.
The council had previously planned to upgrade Vista when it moved over to a new head office in March 2008. However, as Computer Weekly has previously reported, Newham found that some of its core applications were not Vista-certified. Newham will now begin a pilot of Windows Vista, with a view to rolling out the new operating system in 2009.
"One of the big issues with a Vista rollout is application compatibility. You're not sure what is compatible and what is not, which can be daunting when you have thousands of applications. In successful deployments people take a lot of time in planning and testing application compatibility," said Dale Vile, analyst at Freeform Dynamics.
