Project Summary

Developed an application architecture and systems design, for a major systems upgrade.

Background

Having developed an application suite internally, there was, due to a major technology announcement, new price/performance criteria that could easily justify replacing the current mainframe with a newly announced configuration.  The higher performance of the new equipment opened up new opportunities for organizing the application infrastructure.

Requirement

Provide an application and software system strategy, and a detailed migration plan.

Approach

Review system documentation. Replace obsolete documentation with up-to-date versions by  defining the new documentation requirements and project managing the technical writing.

Develop an “As Is” architecture showing all the applications and data, interrelationships, locations, run cycles, backup and recovery plans and processes, to identify bottlenecks and opportunities.

Conduct workshops with the IT staff to develop a “To Be” architecture,  with run cycles and new backup and recovery plans. Wrote a migration plan and managed the migration.
