What is the purpose of performing a partial test upgrade of the application?
As part of the preparation stage, it is important to perform a partial test upgrade of the application to determine or detect each of the following: • Upgrade process speed. The time consumed by the upgrade of a part of the application can provide an idea of the time required to upgrade the entire application. This information is useful for the upgrade procedure planning. • System resources. The available system resources, especially the amount of system memory, can be evaluated using a part of the application. The consumption of system resources is affected by the application complexity; if system resources show signs of excessive usage, such as extreme memory swapping (referred to as thrashing), the resources should be increased. • Setup problems. Common setup problems, such as unavailable third-party components or out-of-date source code, can be detected in a partial test upgrade. • Other common errors. Source code issues can be identified and corrected before the full upgrade of th
