|
|
User stops using the old system and begins using the new system on a certain date
|
|
|
Only one location in the organization uses the new system-so that it can be tested. After the pilot site approves the new system, other sites convert using one of the other conversion strategies.
|
|
|
Each site converts at a separate time. Larger systems that have multiple sites.
|
|
|
Consists of running the old system alongside the new system for a specified time
|
Detailed explanation-1: -Parallel conversion-Each site converts at a separate time. Larger systems that have multiple sites.
Detailed explanation-2: -Phased (modular) conversion: Part of the new system is introduced while the rest of the old one remains in use. This localizes problems to the new module so support resources can focus on it. However, there can be interface issues where modules share data.
Detailed explanation-3: -The possible types of conversion are standard conversion, no conversion, and user-defined nonstandard conversion.
Detailed explanation-4: -In the phased conversion approach, the system is installed sequentially at different locations. Gradually, the conversion process spreads across all locations until all have been converted. Simultaneous conversion means that all locations are converted at the same time.
