After the deployment manager is migrated and restarted, you can perform the actual migration of its federated application server nodes by running the JCL jobs that you generated. When you generated your custom migration jobs, you also created customized instructions for preparing and running the migration jobs in the BBOMMINS members of the CNTL data set that was used to generate your jobs. Follow these customized instructions to complete the process of migrating your federated nodes to Version 6.1.
All other jobs must be submitted by a user ID that has control over the file system.
If necessary, you can now roll back the federated node that you just migrated. See Rolling back a managed node.
For help in troubleshooting problems when migrating, see Troubleshooting migration.
You must stop the Version 5.x or 6.0.x federated node before proceeding.
In order for the application server node to be properly migrated, the deployment manager must be running. In order for this migration to work, the deployment manager must be up and listening on its SOAP port.

Ensure that the WebSphere Application Server Version 6.1.x copy of the code is running. Under "About your WebSphere Application Server," the build number should begin with W61. |
Before you perform the migration, Version 6.1.x requires that a configuration file system be present for your new configuration. You can run BBOMMHFS or BBOMMZFS to create and mount a new configuration file system, or you can mount one manually. Either way, you must have a file system for your Version 6.1 configuration created and mounted before you proceed. This configuration file system is the target of the migration; your Version 5.x or 6.0.x configuration file system is the source.
BBOMMHFS or BBOMMZFS creates a mount-point directory, allocates the configuration's file system, and mounts the file system at whatever value you specified for the mount point when you generated your migration jobs.
Before you proceed, ensure that you have allocated, created, and mounted your configuration file system data sets either manually or using BBOMMHFS or BBOMMZFS. The mount point should be owned by the WebSphere Administrator user ID and have permissions of at least 755. The new configuration file system structures should be included in BPXPARM so that they will be mounted at the next IPL.
BBOWMG1F enables all servers on the federated application server node being migrated to start in PRR processing mode. PRR processing mode resolves any outstanding transactions, clears the transaction logs, and terminates the server. BBOWMG2F disables PRR mode and returns all servers to normal operating state.
The migration utility BBOMMCP copies the generated JCL procedures to start the servers to the specified procedure library. Your Version 6.1.x configuration must use different JCL procedures from those used by your Version 5.x or 6.0.x configuration. This utility will update the new Version 6.1.x configuration, substituting your new JCL names in place of the names that existed in your original Version 5.x or 6.0.x configuration.
Submit BBOMMCP, and verify a return code of 0.

You can use the BBOLOGSD and BBOLOGSA jobs that were created during Version 5.x or 6.0.x customization if you configured the server initially to use the log stream.

If you are migrating nodes in a sysplex, follow this procedure for each federated node that you migrate.
BBOWMG3F is the job that performs the physical migration of the Version 5.x or 6.0.x node to Version 6.1.x based on the information that you supplied when you generated your migration jobs. Submit BBOWMG3F, verify that you are getting return codes of 0, and review the log files in the temporary migration directory on the configuration file system. The migration temporary directory is temporary_directory_location/nnnnn, where temporary_directory_location is the directory specified for the temporary directory location (/tmp/migrate by default) and nnnnn is the numeric value generated for the migration identifier when you generated your migration jobs.
Ensure that all federated nodes in the same cell on this LPAR are shut down.
WebSphere Application Server for z/OS Version 6.1.x requires that the daemon process be at the highest level of code of any of the servers that it manages on the same LPAR. It will be at the Version 6.1.x level when this federated node is started. If there are any additional nodes on the same LPAR and in the same cell as this migrated managed node, you must update the additional down-level node's daemon JCL procedure to STEPLIB to both the Version 6.1.x libraries and those of the highest-level of the down-level nodes.
If you are migrating from Version 5.1 and you have an additional application server node on the same LPAR and in the same cell, for example, add the following to both your Version 6.1.x and Version 5.1 daemon JCL procedure's "Z" member ("Z=BBO5DMNZ" ) using your library names:
//*STEPLIB Setup //* //STEPLIB DD DSN=hlq61.SBBOLD2,DISP=SHR // DD DSN=hlq61.SBBOLOAD,DISP=SHR // DD DSN=hlq61.SBBOLPA,DISP=SHR // DD DSN=hlq51.SBBOLD2,DISP=SHR // DD DSN=hlq51.SBBOLPA,DISP=SHR //*
After you migrate all nodes to Version 6.1.x and before you remove the previous version's libraries from the system, you must update the daemon JCL procedure and remove the previous version's libraries from the STEPLIB concatenation. Failure to do so will result in a failure of the daemon to start.
BBOO0019I INITIALIZATION COMPLETE FOR WEBSPHERE FOR z/OS CONTROL PROCESS BBON001
Use the existing command that you would use to start a Version 5.x or 6.0.x application server, but replace the RACF STARTED procedure name with the value that you entered in the federated node panel for the controller procedure name when you generated your migration jobs. This command starts the Version 6.1.x federated application server. Wait until the server is finished initializing before proceeding.

At this point, your migration to Version 6.1.x is complete.
