Migrating Legacy Systems Four Reasons

Write four reasons to migrate the legacy system

1. Scrap the system completely: This is the case when system is not making an effective contribution to business processes and business processes have changed significantly and the organization is no longer completely dependent upon the system.

2. Continue maintaining the system: This option is used when system is still required, it is stable, and requirements are not changing frequently

3. Transform the system in some way to improve its maintainability: this option is exercised when system quality has been degraded and regular changes to the system are required.

4. Replace the system with a new system: this path is taken when old system cannot continue in operation and off-the shelf alternative is available or system can be developed at a reasonable cost.
