Planning the i5/OS data migration
The time you spend planning for your i5/OS® data migration can help minimize your downtime and make performing the migration easier.
You can view planning tasks or create a customized planning checklist using the information available in the Planning topic of the IBM® Systems Hardware Information Center. To use this information, you need to know specific information about your order, such as model release, features, and any additional solutions you have ordered. Return to this topic when you have completed the planning tasks in the checklist for your environment. Before you can migrate your data, do the following:
Plan for the hardware, which includes the following:
- Ordering the target system with feature code 0205.
This feature code ensures that the target system is set up for the data migration and entitles you to run the new operating system on both the source and target systems for a maximum of 70 days so that you can complete the data migration. You must reinstall the previous operating system on the source system after the data migration is complete.
- Identifying disk storage requirements.
You must ensure that you have enough disk storage capacity for the new operating system and for the data from the source system, as well as for any new data and software planned for the target system.
- Identifying any tape incompatibilities.
You must ensure that you have a tape drive that is compatible with the target system. To determine if your tape drive is compatible, see the Storage Solutions Web site or the System Handbook. To learn more about tape devices, see the Tape topic.
- Ensuring that you have a physical plan for the target system.
The target system is going to be set up and running beside the source system for a period of time. There are physical planning and setup implications that pertain to the target system.
Plan for the software, which includes the following:
- Evaluating disk storage space requirements.
You must ensure that you will have adequate disk storage before you start to install or replace software.
- Identifying possible upgrade paths for licensed programs.
When you install the new release of the i5/OS operating system, some licensed programs may no longer work. You should identify licensed programs that are no longer available at this release and their replacements where applicable. Additionally, to avoid losing data that depends on these licensed programs, migrate the data from your system to an accessible location before installing the new release.
Plan for your connection, which includes the following:
- Choosing a console.
If you are using a twinaxial console on the source system and using Operations Console on the target system, ensure that you have a twinaxial controller for any twinaxial devices you plan to run from the target system.
When you have completed these tasks, you should have a final data migration plan that includes the following:
When you are finished IBM Migration Services can help you in planning and migrating your data to the latest models. For more information, see the IBM Migration Services Web site.
The next step is to perform the migration.
