Past versions of Web Server were delivered in two ways:
File-based format, packed in a ZIP distribution
Package-based format, included in past Java ES releases
Direct migration from a Web Server version lower than 6.0 is not supported. See Installation, Migration, and Upgrade Notes in Sun Java System Web Server 7.0 Update 6 Release Notes for more information.
To support these past practices, Web Server provides three upgrade paths to version 7.0 Update 6:
Upgrading from a file-based ZIP distribution of version 7.x
Upgrading from a package-based distribution of version 7.x (Java ES 5 and 5 Update 1)
Migrating from version 6.x
The remainder of this section explains the following topics:
Upgrading from a File-Based ZIP Distribution of Web Server 7.x
Upgrading from a Package-Based Distribution of Web Server 7.x
This installation program provided with Web Server 7.0 Update 6 can identify and upgrade Web Server file-based installations back to version 7.0.
Before Upgrading – Before using the Web Server 7.0 Update 6 installer to upgrade an older 7.x file-based installation, you should review Installation, Migration, and Upgrade Notes in Sun Java System Web Server 7.0 Update 6 Release Notes and Migration and Upgrade in Sun Java System Web Server 7.0 Update 6 Release Notes .
To Upgrade – To upgrade a Web Server 7.x file-based installation using the Web Server 7.0 Update 6 installer, see Upgrading the Web Server from 7.0 to 7.0 Update 6 in Sun Java System Web Server 7.0 Update 6 Installation and Migration Guide.
To upgrade from the package-based distribution of Web Server 7.0 (in Java ES 5) or 7.0 Update 1 (in Java ES 5 Update 1) to version 7.0 Update 6, apply the patches for the appropriate platform, as described in Upgrade in Sun Java System Web Server 7.0 Update 6 Release Notes. Before downloading and installing the patches, you should review Migration and Upgrade in Sun Java System Web Server 7.0 Update 6 Release Notes, also in Sun Java System Web Server 7.0 Update 4 Release Notes.
Note that the upgraded installation is not exactly equivalent to installing the file-based ZIP distribution of version 7.0 Update 6 because it represents a package-based upgrade, not a file-based installation.
Web Server 6.0 and 6.1 configurations can be migrated to 7.0 Update 6. Direct migration from a Web Server version lower than 6.0 is not supported. Earlier versions such as Web Server 4.0 or later must first be migrated to Web Server 6.1, then to Web Server 7.0. Follow these steps to migrate from Web Server 6.x versions:
Install Web Server 7.0 Update 6, as described in Chapter 2, Installing the Web Server, in Sun Java System Web Server 7.0 Update 6 Installation and Migration Guide.
Migrate 6.x server instances to 7.0 Update 6, as described in Chapter 5, Migrating to Web Server 7.0, in Sun Java System Web Server 7.0 Update 6 Installation and Migration Guide.
