2 Stages of Legacy Modernization Metadata enablement of a four-stage approach end-to-end Modernization

3 Stages of Legacy Modernization The speed of technology changes, coupled with the growing requirement for intra-organization software collaboration, makes modernization a must for survival Some companies have followed a non-invasive approach for altering the application surface with eai and other approaches that utilized screen-scraping, generated interfaces, etc. Some non-invasive projects have now evolved to cause a new level of complexity the old code is still spaghetti and now there are additional layers of interdependencies It is time to modernize the right way and recover manageable architectures end-to-end Modernization

11 Market view! Business rule and component method mining support the move to.net, Java and more agile application development Business view Metadata Driving Modernization Stages! Managing d logic separately from applications " Can keep content in synch with single source maintenance " gives users power over their own changes " frees IT for technology challenges Technical View! Software code modernization can be automated " Understand code and clean coding anomalies, dead code, dead data " code mine logic as component and/or rules " Transform code to new languages and/or to new technologies and platforms " Manage modernized & discovered reusable software Future View! Standards and managed process play a critical role " ITIL, MOF, CWM, W3C, SOAP, XML, WSDL, OMG (Legacy Transformation group) " Work Flow, repositories, application portfolio management " ASG XMI standard and SOA tool framework end-to-end Modernization
