Upgrade All 

Maintains a consistent version for all components in your deployed system 

Maximizes the number of components to upgrade 

The choice between Selective Upgrade and Upgrade All is not rigid. For example, you might choose to selectively upgrade the product components on a particular computer, but wish to upgrade all shared components needed to support the selected product components.In fact, for upgrades from Release 4 to Release 5, selectively upgrading product components, while upgrading all of the corresponding shared components, is often the preferred approach.
