Scenarios: Data migration
These scenarios show different migration situations for moving data to another system.
- Migrating from IBM® i V6R1 or IBM i 7.1 on a Power Systems model 520 to IBM i 7.2 on a Power Systems model 720 system
- In this scenario, you have a model 520 system,
you are running IBM i V6R1,
and you want to migrate your data to a Power Systems model 720.
What to do:
You cannot install IBM i 7.2 on your model 520. To migrate your data, you need to save the data to a tape drive that is compatible with model 720 and then restore the data on the model 720.
To perform this data migration, complete the steps in the following topics:
- Migrating from IBM i V6R1 on a Power Systems POWER6® 520 to IBM i 7.2 on a partitioned Power Systems model 720
- In this scenario, you have a Power Systems POWER6 520, you are running V6R1, and you
want to migrate your data to an IBM Power Systems model 720.
What to do:
To migrate your data, you need to install IBM i 7.2 on your POWER6 520. You then need to install IBM i 7.2 on all logical partitions on your model 720, save the data from each logical partition to tape drives that are compatible with the model 720, and restore the data on the model 720. Configure and prepare logical partitions on the model 720 before the data migration.
To perform this data migration, complete the steps in the following topics:
- Upgrading to a new version of IBM i on your system
- In this scenario, you are running IBM i V6R1 or 7.1 on your
system and you want to upgrade to IBM i
7.2.
What to do:
If you are upgrading to a new version of IBM i on the same system, it is not necessary to perform an explicit data migration. You can follow the steps in Checklist: IBM i software upgrade or replacement readiness to upgrade to IBM i 7.2.
- Upgrading your system to a new IBM Power Systems model
- In this scenario, you want to upgrade your system to a newer model.
What to do:
If you are upgrading to a new IBM Power Systems model without changing the serial number, it is not necessary to perform an explicit data migration. You can follow the directions in the Upgrading the system and data migration topic for your system model in the IBM Power Systems Hardware Information Center.
If you are moving hardware to your new system, then your data will transfer. If your hardware is not compatible with your new system, you can perform a data migration.
To perform this data migration, complete the steps in the following topics:
- Migrating data from one logical partition to another
- In this scenario, you want to migrate data from
one logical partition to another on your system.
What to do:
If you are migrating data from one IBM i logical partition to another logical partition on the same system, follow the instructions in Restoring a logical partition (LPAR) to another LPAR–Checklist 22.
