TruTek’s Migration Methodology
• Application code is normally easy to migrate. SQL needs to be changed.
• Changes to the existing application (deltas) should be incorporated at the end of the migration.
• Exclude schema and application changes from the scope of the project. Stick to an "as is"port.
Follows the traditional"waterfall" System Life Cycle (SLC) approach rather than the "iterative" Rapid Application Development (RAD) approach. However, four to six week DB prototypes or one to two week AS prototypes are often part of the migration Requirement gathering, analysis and design are normally completed in two to ten weeks for DB migrations. Even less for AS migrations (one day to one week) Easiest part for DB migration is installation scripts, schema and data (normally two to eight weeks).
Migration Challenges-Schedule & Cost Migration Challenges-Schedule & Cost
• Migration Experience
– Staff typically does not have specific migration experience
• Knowledge & Training – Little or no knowledge of the new destination platform/s
– Lead time for training and skills development
• Research & Development Effort – Large investment in learning and developing new and unproven techniques
• Not Primary Business Activity – Migrations takes resources away from your primary business objectives
• Developer & DBA Fear – More so DBA…I am no longer the guru, I have to learn a new
