Migrate from V4 to a V6 deployment manager with the Migration wizard
V6 migration always works by migrating an earlier supported version of WAS to a deployment manager profile.
Before you begin
Collect the following information about your V4 installation before you begin this procedure. The Migration wizard prompts you for the information during the migration.
Legend: Supported versions and their keys in the following table are:
- IBM WAS Advanced Single Server Edition, Version 4.0.2 and later (V4.0.y AEs)
- IBM WAS Advanced Edition, V4.0.2 and later (V4.0.y AE)
- IBM WAS Enterprise Edition, V4.1 and later (V4.1.y EE)
Table 1. V4 information that is required Panel and field in wizard V4 product Record your value here Link to description of field V4.0.y AEs V4.0.y AE V4.1.y EE Installation root directory Yes Yes Yes See WASPreUpgrade command for a description of the currentWebSphereDirectory parameter. Configuration file name Optional: Defaults to config/server-cfg.xml file. No Required. The name of the XML configuration file to process. See WASPreUpgrade command for a description of the import parameter.
Use port values assigned to previous installation? Optional; defaults to false. Optional; defaults to false. Optional; defaults to false. Specifying “true” causes any ports of matching VirtualHosts to first be removed from the new configuration before adding the new values.
Specifying “false” for this parameter will just add new port values.
See WASPostUpgrade command for a description of the replacePorts parameter.
Before using the Migration wizard, have access to the existing, previous version of WebSphere Application Server. You must also have a valid V6 deployment manager profile to serve as the target of the migration.
You should have installed Version 6 already. Use the Profile creation wizard to create a new target profile if the deployment manager target for the migration does not yet exist. After verifying that a valid V6 target exists, one can start the procedure.
Note: You must use the same cell name in V6 that you used in V4.0.x. It is recommended, though not required, that you use the same node name as well.
The Network Deployment product does not create a deployment manager profile during installation because there are three profile types that you might require on any machine. The Installation wizard prompts you to use the Profile creation wizard at the end of installing the core product files. However, using the Profile creation wizard at that time is optional.
Create a deployment manager profile if you have not already created one.
Overview
This topic describes using the Migration wizard to migrate a Version 4.x Application Server to a V6 deployment manager.
The Migration wizard is new as of V6. The wizard is the graphical interface to the V6 migration tools, which are the WASPreUpgrade command and the WASPostUpgrade command. The migration tools are command line tools.
You must supply the following V6 information about the target deployment manager profile during the migration:
Table 1. Version 6 information Panel and field in wizard Record your value here Link to description of field Backup directory name See WASPreUpgrade command or WASPostUpgrade command for a description of the backupDirectoryName parameter. Profile name See WASPostUpgrade command for a description of the profileName parameter. After gathering all of the information that is required during the migration, use the wizard to migrate a V4.x Application Server to the V6 deployment manager.
Procedure
- Start the First steps console.
Use the First steps console to start the deployment manager. The command to start the First steps console for the deployment manager profile is at this location:
- ./install_root/profiles/dmgr_profile/firststeps/firststeps.sh
- install_root\profiles\dmgr_profile\firststeps\firststeps.bat
- Click the Migration wizard option on the First steps console.
The First steps console starts the Migration wizard. The wizard displays its Welcome panel.
- Read the Welcome panel to learn about the migration, then click Next.
The wizard displays the Detected versions of WebSphere Application Server panel.
- Select a previous version, then click Next to continue.
Select the check box to specify the location of a previous installation that might not appear in the list. V4.0.y AEs requires you to identify the location of the configuration file. You do not need to identify the location of the configuration file for other V4 editions.
The default location to use for the previous installation varies depending on the V4.x product that you have installed. The following list shows default locations:
- IBM WAS Advanced Single Server Edition, Version 4.0.2 and later (V4.0.y AEs) uses a default location for the config\server-cfg.xml file.
- IBM WAS Advanced Edition, V4.0.2 and later (V4.0.y AE) uses the output from the XMLConfig tool. You must have the Advanced Edition admininstrative server running during the migration.
- IBM WAS Enterprise Edition, V4.1 and later (V4.1.y EE) uses the location of the product that it is extending, which can be either AEs or AE.
If the previous version specification is correct, the wizard displays the Migration backup directory panel.
- Specify a backup directory, then click Next to continue.
If the V6 profile is valid, the wizard displays the Target profile selection panel.
- Select the target profile from the list of valid profiles for the installation, then click Next.
Use the Profile creation wizard to create a target deployment manager profile for the migration if one does not yet exist.
Installing the Network Deployment product does not automatically create a profile.
The wizard displays the Port value assignment panel.
- Choose whether to use port values assigned to the previous installation, or to generate new V6 port values that are already assigned to the target profile, then click Next.
The wizard displays the Deployment manager verification panel that warns you to verify that the deployment manager is running.
- Verify that the V6 deployment manager is running, then click Next.
The wizard begins the premigration. The wizard displays a Migration status panel during the premigration.
If the premigration is not successful, the wizard displays a failure panel. If the premigration is partially successful, the wizard displays a warning panel.
Correct any problems and retry the migration.
If the premigration is successful, the wizard displays an indication of success.
- Click Next to start the postmigration.
If the postmigration is not successful, the wizard displays a failure panel. If the postmigration is partially successful, the wizard displays a warning panel.
Correct any problems and retry the migration.
If the postmigration is successful, the wizard displays an indication of success.
- Click Finish to exit the migration wizard.
