Setting up for primary migration

Edit online

About this task

Complete the following steps to setup for a primary migration.

Procedure

  1. Create a Migration session with the H1 volumes as the primary volumes that you want to migrate and the H2 volumes as the volumes on the new storage system. For more information, see Creating a Migration session and adding copy sets.
  2. Setup the Copy Services Manager server to communicate to a z/OS® system or sysplex for HyperSwap management. For more information, see Setting up the environment for HyperSwap.
  3. From the Session Actions list, select Commands and issue the StartGC H1->H2 command. This command creates a Global Copy relationship between the current primary volumes and the new volumes.
  4. From the Session Actions list, select View/Modify > Properties and on the H1-H2 options tab make the following changes and click OK to save the changes.
    1. Under z/OS Management, choose the system or sysplex name that has all the primary volumes that are attached to it. Only set the sysplex association when you also change the following Manage H1-H2 Migration with HyperSwap option.
    2. Check the box next to Manage H1-H2 Migration with HyperSwap.
    Note: After you update the properties, confirm that a HyperSwap configuration is loaded with the pairs in the session on z/OS. On the sessions page, the session details must indicate HyperSwap Yes and the dynamic image must indicate that HyperSwap is enabled between the sites.

What to do next

Perform the swap when the progress for the H1-H2 role pair is 99% or greater. Depending on the type of environment, complete one of the following to perform the swap.
