Upgrade Objectives and Priorities

An upgrade plan reflects your upgrade objectives and priorities, which often depend on the scope and complexity of your existing deployment architecture.

For example, your Java ES deployment architecture might consist of a single Java ES product running on a single computer, and your upgrade objective is to fix some bug in the previous software release. On the other hand, your Java ES deployment architecture might consist of a number of interoperating Java ES products deployed across a number of different computers, and your upgrade objective is to achieve some new functionality by upgrading the minimum number of products required to achieve that end with minimal downtime.

In general, the greater the number of Java ES products and computers in your deployment architecture, and the more ambitious your upgrade objectives, the more complex will be your upgrade plan.
