Case Studies: Project Tokologo - City of Tshwane
EBE Computing recently completed a key migration effort by helping the City of Tshwane (formerly Pretoria, the administrative capital of South Africa) move decades of investment in the legacy backend to a Windows 2000 system. The City was faced with the obviation of support for their ICL mainframe, and were confronted with the prospect of an expensive, unbudgeted, hardware grade. The City now successfully uses the OpenSCL migrated environment.
Clients Situation
n Tshwane had been using its ICL mainframe since the early 1980s and it hosts the primary systems for their billings, reconciliations, and other backend functions
n ICL advised the organisation of the cessation of hardware support for the mainframe. Tshwane was given a six-month notice.
n The alternative supplied to Tshwane was to upgrade to a Nova-series mainframe, at considerable incremental expense to the organisation.
n Since running mission-critical backend applications on unsupported hardware was not an option, Tshwane could not get away by “doing nothing”
n Options for maintaining continuing operations were narrowed down to three (3) choices:
n Upgrade to a new ICL mainframe
n Manual migration of mainframe applications (1.2m lines of code) to a server platform
n OpenSCL-supported migration to Windows 2000 server platform
