Upgrading to GlassFish Enterprise Server 2.1.1

GlassFish Enterprise Server supports upgrade from a variety of products:

• GlassFish v2/2.1

• Sun Java System Application Server: file-based and package-based distributions

• Sun Java System Application Server, Enterprise Edition: file-based and package-based distributions

• Sun Java System Application Server, Platform Edition

For a complete list of the products, versions, and distributions that are supported for upgrade, see Upgrade Overview in Sun GlassFish Enterprise Server v2.1.1 Upgrade Guide.

GlassFish Enterprise Server 2.1.1 is functionally equivalent to GlassFish Enterprise Server 2.1 Patch 6. If you have already performed the 2.1P6 patch upgrade, you do not need to perform the 2.1.1 upgrade.

To support the various products and distributions, GlassFish Enterprise Server offers four upgrade paths:

• Side-by-side upgrade of a file-based ZIP installation

• In-place upgrade of a file-based ZIP installation

• Upgrade of a package-based installation

• Upgrade of a package-based installation to a file-based ZIP installation

These upgrade paths, and the instructions for following them, are described in Chapter 2, Upgrading an Enterprise Server Installation, in Sun GlassFish Enterprise Server v2.1.1 Upgrade Guide.

Before performing an upgrade to GlassFish Enterprise Server 2.1.1, you should review Chapter 1, Enterprise Server Compatibility Issues, in Sun GlassFish Enterprise Server v2.1.1 Upgrade Guide and Upgrading the Enterprise Server in Sun GlassFish Enterprise Server v2.1.1 Release Notes.
