You can migrate an existing Web server and Web server plug-in
to support the current version of the product.
What to do next
The steps to perform
next depend on whether you are migrating from Websphere Application
Server 5.1.x or 6.x. Web server definitions did not exist for 5.1.x.
Therefore, new definitions need to be created for Version 7.0. Web
server definitions did exist for 6.x and are migrated if the definitions
were created against a managed node.
Migrating from WebSphere Application Server Version 5.1.x:
In Version 6.0 and later, the plug-in configuration
file has a one-to-one relationship with a Web (application-centric)
server instead of a single global plug-in configuration file (topology-centric
or cell-wide).
Migrating from WebSphere Application Server Version 6.x:
The following actions only apply
if you are migrating from WebSphere Application Server
Version 6.x, complete the following actions. This information does
not apply if you are migrating from Version 5.1.x.
Web server
definitions are migrated for managed nodes but not for unmanaged nodes.
Nodes controlled by the IBM HTTP Server Administration Server are
unmanaged nodes.
- For a Web server defined on a managed node, the Web server definitions
continue to work if the new Web server is installed to the same directory
as the previous Web server version. If the Web server is installed
to a different directory, the path to the Web server needs to be updated
within the definition.
- For a Web server defined on an unmanaged node, manually complete
one of the following actions to create the Web server, and set up
the application mappings:
- While running the administration console wizard, select the Mapping
ALL option to generate mappings to all applications that
are installed during the Web server creation process.
- Issue the following wsadmin command, and reply ALL to
the mapping applications prompt:
$AdminTask createWebServer -interactive
- Run the configureWebserverDefinition.jacl script.
This script
maps all installed applications to the Web server. The script updates
all of the information related to the Web server plug-in such as the
locations of the plug-in installation root, log file, configuration
file, and key stores on the Web server system. However, the script
does not update other properties related to the Web server if the
Web server definition already exists.
