2 install websphere application server version 80

2. Install WebSphere Application Server Version 8.0.
Read the "Installing the product and additional software" article in the information center for more
information.
3. Use the Profile Management tool or the manageprofiles command to create a WebSphere
Application Server Application Server Version 8.0 profile.
Read the "Creating profiles using the graphical user interface" article or the "manageprofiles
command" article in the information center for more information.
4. Run the WASPreUpgrade command, specifying the migration backup directory name and the
existing WebSphere Application Server Application Server directory name.
Read “WASPreUpgrade command” on page 26 for more information.
The WASPreUpgrade tool saves selected files from the /bin directory to a backup directory you
specify on a wizard panel. Migration saves files from the following directories to the backup
directory:
– classes
– config
– installableApps
– installedApps (or an alternate directory specified by the user)
– properties
5. Run the WASPostUpgrade command, specifying the migration backup directory.
Read “WASPostUpgrade command” on page 29 for more information.
The WASPostUpgrade tool copies the environment in the backup directory to the WebSphere
Application Server Application Server Version 8.0 stand-alone application server installation.
Note: When migrating a stand-alone application server from Version 6.x or 7.x to Version 8.0, you
can choose a stand-alone application server node that has already been registered with an
administrative agent as the target of the migration.
Migrating to a Version 8.0 stand-alone application server on a remote
machine
Use the migration tools to migrate from a Version 6.x to a Version 8.0 stand-alone application server on a
remote machine.

Migrating, coexisting, and interoperating

Before you begin
Read “Overview of migration, coexistence, and interoperability” on page 1 and “Premigration
considerations” on page 5.
Typically, you can use the WASPreUpgrade and the WASPostUpgrade migration tools to upgrade from
Version 6.x to Version 8.0 on the same machine. However, some scenarios require that you migrate the
Version 6.x configuration on one machine to Version 8.0 on a different machine. One of these scenarios is
when you install new machines for your Version 8.0 environment but need to migrate your existing Version
6.x configuration from other machines.
To ensure that your operating system is supported by WebSphere Application Server Version 8.0, visit the
following site for the most current list of supported hardware and software: WebSphere Application Server
system requirements.
If you find that your operating system is not supported for migration to Version 8.0, read “Migrating
stand-alone application servers from unsupported operating systems” on page 38.
The WASPreUpgrade command saves the existing Version 6.x configuration into a migration-specific
backup directory. The WASPostUpgrade command uses this directory to add the old configuration settings
to the new Version 8.0 environment.
