    Has anyone out there used the IBM i Migrate While Active offering to take an on-premises IBM i environment up to PowerVS? I'd like to know your experiences. Good points, bad points, pitfalls, etc.

    Hi Matthew

    Here are my thoughts, I hope they are helpful:

    • Have I used it? - Yes but not to migrate to PowerVS 
      It works  just as well with other cloud and On Prem servers

    • Tips for planning stage with PowerVS
      Ensure you have spare capacity on the Internet Connection you plan to use for Sync to PowerVS
      If you have a big or busy system, consider a separate, dedicated connection
      Design your post migration network connection before starting the migration so you can more easily test
      Ensure you are using DNS names for connecting to the source system from all client connections to allow for swift change at cut over
      Design you UAT cutover testing plan
      Monitor the MWA system interface regularly to make sure you are consistently getting close to being in Sync, as some workloads periodically generate large volumes of new data that may take longer to sync.
      Use the MWA option to Test your Sync's workload at least twice before final cut over. 

    • Pitfalls
      Make sure you have considered the licensing for your 3rd Party software tools.
      Not only will your serial number change, it's highly likely your model, processor feature and processor group will change too
