Preparing to migrate a WebSphere Application Server, Network Deployment cell for z/OS

Before migrating a WebSphere® Application Server, Network Deployment cell to WebSphere Application Server Version 7.0 perform the following actions: inventory your existing configuration, plan your node-by-node strategy, and generate the CNTL and DATA datasets that you will use in the actual migration.

Before you begin

Read Overview of migration, coexistence, and interoperability and Premigration considerations.

WebSphere Application Server Version 7.0 supplies migration jobs in the target dataset that you allocate when you generate your migration jobs. Use these jobs to perform the actual migration.
  • BBOMDHFS or BBOMDZFS
  • BBOWMG3D
  • BBOWDPRO
  • BBOWDPRE
  • BBOWDPOS
  • BBOMDCP

Procedure

  1. Inventory your configurations.
    Enter the values for your configurations on a printed copy of the following tables:
    • WebSphere Application Server for z/OS® Version 5.1.x or Version 6.x configuration general information:
      Table 1. Configuration values. . Table containing configuration values.
      Item Value                                                              
      Cell short name:  
      Cell long name:  
      Sysplex name:  
      Configuration file system strategy:

      __ All nodes share one file system

      __ Unique file system per node

      Job Control Language (JCL) start procedure strategy:

      __ Use common JCL

      __ Unique JCL per server

      Location of original Version 5.1.x or Version 6.x configuration datasets:  
      WebSphere Application Server Version 5.1.x or Version 6.x home directory (configuration file system):  
      You also need a WebSphere Application Server for z/OS administrator user ID and password.
    • WebSphere Application Server for z/OS Version 5.1.x or Version 6.x deployment manager node:
      Table 2. Deployment manager node values. . Table containing deployment manager node values.
      Item Value                                                              
      Configuration mount point:  
      Configuration file system dataset:  
      Home directory:

      Default:/DeploymentManager

      Your value: ___________________

      WebSphere Application Server SMP/E home:

      Default: /usr/lpp/zWebSphere/V6R1

      Your value: ____________________

      Controller JCL start procedure:  
      Servant JCL start procedure:  
      Daemon JCL start procedure:  
    • WebSphere Application Server Version 7.0 installation information:
      Table 3. Version 7.0 installation information. . Table containing version 7.0 installation information.
      Item Value                                                              
      Product dataset HLQ:  
      Product directory (SMP/E target for Version 7.0):  
      WebSphere Application Server Version 7.0 in LPA/LNKLST?:

      __ No

      __ Yes

  2. Plan the node-by-node migration strategy.
    Map out your migration sequence on a printed copy of the following table:
    Table 4. Migration Sequence. . Table containing a migration sequence
    Item Node Short Name System Name
    Deployment manager node    
    Second node    
    Third node    
    Fourth node    
    Fifth node    
    Sixth node    
  3. Produce migration CNTL and DATA datasets for each node that you want to migrate.

    You must provide a set of CNTL and DATA datasets for the migration utilities to read in order to perform the migration. Generate a set of customized jobs for each node in your configuration that you want to migrate.

    Graphic depicting migration CNTL/DATA data sets.

    Some important points about these steps:

    The purpose of creating these customized CNTL and DATA datasets is to give the migration utilities access to key information about your new Version 7.0 configuration as well as access to shell scripts customized with this new information. The migration utilities get the bulk of the configuration information from your existing Version 5.1.x or Version 6.x configuration file system.
