WebSphere
Application Server Migration Planning and Best Practices Guide
This section contains Migration best practice recommendations and
Migration issues that have been encountered either through internal IBM
testing or external customer interactions.
WebSphere
Application Server Version 5.1 Information Center
With the Information Center, you can view, browse, and search online
information about WebSphere Application Server in general as well as
information specific to your migration tasks.
WebSphere
Application Server Version 5.0 Information Center
With the Information Center, you can view, browse, and search online
information about WebSphere Application Server in general as well as
information specific to your migration tasks.
Migrating
and coexisting
This Information Center topic describes migrating, which is copying the
configuration from a previous release of a Application Server product into
a new release. This topic also describes coexisting, which is running a
new release of a WebSphere Application Server product on the same machine
at the same time as you run an earlier release.
WebSphere
Application Server for z/OS Migration planning
This link contains additional z/OS® information that will help you plan
and execute your Migration.
Migrating
to WebSphere V5.0 An End-to-End Migration Guide
This IBM Redbooks® publication will assist you in the end-to-end
migration of an Application Server installation. The end-to-end migration
path includes the migration of the development environment,
test/integration environment, and production environment using
software-engineering methodologies. This guide presents the best practices
in migration strategy and planning, migration tools, and practical
migration examples.

Solutions
to migration problems for V5.1
Browse through common V5.1 migration problems and solutions that have
already been documented and published to the Web.
Collecting
data (MustGather)
When a solution cannot be found to your migration problem, you can begin
collecting data (MustGather) before calling IBM support. This will help
you familiarize yourself with the troubleshooting process and save you
time.
Exchanging
information with IBM Technical Support
To diagnose or identify a problem, it is sometimes necessary to provide
Technical Support with data and information from your system. In addition,
Technical Support might also need to provide you with tools or utilities
to be used in problem determination.
Instructions
for handling certain Out of Memory conditions which occur during migration
of an earlier version of WebSphere Application Server to V5.1.1, V6.0.2,
or V6.1
When running WASPreUpgrade or WASPostUpgrade, during the migration
process from an earlier release of Application Server to V5.1.1, V6.0.2,
or V6.1, the heap might run out of memory for a complex environment.
Either the execution of wsadmin to install the applications, or the
migration of the configuration itself, throws java.lang.OutOfMemory
errors.
