A retail chain in Pune replaces its old inventory MIS by running the old and new systems side by side for two months before shutting down the old one. Which implementation approach is this?

This is parallel conversion, where the old and new systems operate simultaneously for a period so outputs can be compared and risk is reduced. It costs more than direct changeover, which switches at once, and differs from phased or pilot conversion that limit the rollout by module or location.

Explanation

Running both systems simultaneously for a period is parallel conversion. It is safer because outputs can be compared, though costlier. Direct changeover replaces the old system at once, and phased conversion introduces the new system module by module.
