Optimum Migration Strategy
 
Migrating mission critical applications from the legacy systems environment to the target  environment is a complex undertaking.  The goal is a smooth migration path from less flexible, more difficult-to-maintain, older systems to ones that use the most appropriate and robust advanced technologies.  A comprehensive plan is necessary to understand and handle the complexity of the migration process.

The OSC’s optimum migration strategy is a phased, incremental approach.  In this manner, the risk typical of an initiative of this magnitude can be successfully managed.  The OSC’s migration strategy includes the following:

This migration strategy will provide the OSC the opportunity to focus on one initiative at a time as well as to stage its information technology investments.  Figure 22 illustrates the migration strategy and its timeframe.
