This Sun Java System Application Server Platform Edition 8.1 Update 2 Upgrade and Migration Guide describes how JavaTM 2 Platform, Enterprise Edition (J2EE™ platform) applications are migrated from the Sun ONE Application Server 6.x/7 (also known as iPlanet Application Server), J2EE Reference Implementation (RI) 1.3 Application Server, Sun Java System Application Server 7 to the Sun Java SystemApplication Server8.1 product line.
This guide also describes differences between adjacent product releases and configuration options that can result in incompatibility with the product specifications. Specifically, this Sun Java System Application Server Platform Edition 8.1 Update 2 Upgrade and Migration Guide details Sun Java System Application Server 8.1 incompatibility with Sun Java System Application Server 8 2004Q2, Sun Java System Application Server 7 2004Q2, and the Java™ 2 Platform, Enterprise Edition (J2EE™ platform), version 1.4 specification.
