Scenarios: Data migration
These scenarios show different migration situations of moving i5/OS® data to another system.
- Data migration scenario 1: Migrating from V5R1 on a model 620 to V5R4 on a model 520 system
- In this scenario, you have a model 620 system, you are running V5R1, and you want to migrate your data to a model 520 system.
- What to do:
- You cannot install i5/OS V5R4 on your 620 system. To migrate your data, you will save the data to a tape drive that is compatible with the model 520 and then restore the data on the model 520. To perform this data migration, first prepare for the migration and then complete the migration.
- Data migration scenario 2: Migrating from V5R1 on a model 740 to V5R4 on a partitioned model 570 system
- In this scenario, you have a 740 system, you are running V5R1, and you want to migrate your data to a partitioned 570 system.
- What to do:
- You can install i5/OS V5R4 on your 740 system. To migrate your data, you first install V5R4 on your 740 system, then save the data to a tape drive that is compatible with the partitioned 570 system and restore the data on the 570 system. To perform this data migration, first prepare for the migration and then complete the migration.
- Data migration scenario 3: Migrating from V5R1 on a partitioned 830 system to V5R4 on an 825 system
- In this scenario, you have an 830 system with multiple V5R1 partitions, and you want to migrate your data to an 825 system.
- What to do:
- You can install i5/OS V5R4 on your 825 system. To migrate your data, you first install V5R4 on all partitions of your 830 system, then save the data from each partition to a tape drive that is compatible with the model 825 system and restore the data on the 825 system. To perform this data migration, first prepare for the migration; then complete the migration.
- Data migration scenario 4: Installing a new version of i5/OS on your system
- In this scenario, you are running V5R2, or V5R3 on your system and you want to upgrade to V5R4.
- What to do:
- If you are installing a new version of i5/OS on the same system, it is not necessary to perform an explicit data migration. You can use the Install the i5/OS release topic to install V5R4.
- Data migration scenario 5: Upgrading your system to a model 890 system
- In this scenario, you want to upgrade to the 890 system.
- What to do:
- If you are upgrading to a new system without changing the serial number, it is not necessary to perform an explicit data migration. You can follow the directions in the Upgrades topic.
- Data migration scenario 6: Migrating data from one partition to another
- In this scenario, you want to migrate data from one partition to another on your system.
- What to do:
- If you are migrating data from one system partition to another partition on the same system, follow the instructions for Restoring a Logical Partition to Another Logical Partition--Checklist 22 in Chapter 3 of the Backup and Recovery Guide.
