There are four methods of system changeover which are as given below:

Direct cutover: In this method, the old system is replaced immediately and newly developed system is deployed. This method is not used for any critical system.

Parallel operation: In this method, the newly developed system and old system works in a parallel manner for a specific time period. After that time period, the old system is removed and all the work is done on new system.

Pilot operation: In this method, the pilot project is used at some specific locations inside the organization. If it is successfully implemented and any problem does not occur, it is implemented all over the organization. The pilot operation also has some time bound...
