In 2012, EmpireCLS needed to build out their new platform that would replace their existing Linux platform lovingly known as Iliad. We termed the new platform “Tranquility” to try and install a sense of calmness for those migrating from the legacy platform.
The existing linux platform had around 1 million lines of code, over 200 applications, and 20 years of data in an ISAM database. Our goal was to build this new web platform on Windows and slowly migrate the individual programs.
From the onset we counted on running both systems side by side and slowly migrating users to the new system. We chose the side by side approach to cut down on risk to the company, simplify training, and allow real-time validation between systems.
The initial modules that were moved were read-only; customer profiles, reservations, chauffeur HR. New modules were added to support credit card rebills, chauffeur check-ins, system monitoring, and several third party integration portals.
