Target Node - Technology Refresh Requirements
Migrating using partition mirroring requires a minimum level of licensed internal code (LIC) be installed on the target node before beginning a migration. The source and target node must be installed with matching levels of LIC.
The following table describes the minimum IBM i Technology Refresh (TR) level required to use the partition mirroring method of migration for each supported release. A Technology Refresh can be downloaded and installed using standard procedures and tools.
| IBM i 7.6 | IBM i 7.5 | IBM i 7.4 |
|---|---|---|
| TR2 (SF99961 - Level 3) | TR7 (SF99951 - Level 10) | TR12 (SF99668 - Level 27) |
Methods for installing LIC on the target node
For additional information about installing LIC on a new logical partition, see Installing Licensed Internal Code on a new logical partition.
Some options for installing LIC on the target node before beginning a migration using partition mirroring include:
- Use a recent SAVSYS or full system save of the source node
Tip: Install the latest Db2 Mirror PTF group and all recommended fixes for the target node (table below) on the source node before the save. Then follow the instructions for installing LIC on a new logical partition. - Download and use an IBM provided image that meets the minimum requirements.
Tip: Download the latest IBM i TR resave and then follow the instructions for installing LIC on a new logical partition. Then apply all recommended fixes for the target node (table below). - Use a preinstalled version of LIC (manufacturing preinstall or cloud image deploy) that meets the minimum requirements.
Tip: Verify the required TR level and all recommended fixes for the target node (table below) are installed.
NOTE: A LIC only install is acceptable, meaning that you are not required to install the full IBM i operating system on the target node. However, if the image used to install the target node does not contain the recommended fixes for the target node (table below), then you must install the full IBM i operating system so you can then apply the recommended fixes.
Target Node - Recommended Fixes
The fixes in the table below should be applied on both the target node and the source node before beginning a migration using partition mirroring.

Target Node - Storage Requirements
The storage capacity assigned to SYSBAS on the target node must be equal to or greater than the amount of allocated (used) storage of SYSBAS on the source node. The individual disk unit sizes and types do not need to match. The number of disk units does not need to match.
If the source node has one or more user auxiliary storage pools (ASPs), then you must configure the same user ASPs (2-32) on the target node before starting partition mirroring. Partition mirroring replicates SYSBAS and all basic user ASPs together.
If the full IBM i operating system is installed on the target node, you can use Navigator for i to configure disk units on the target node. Follow the instructions here: Adding a disk unit or disk pool.
If only LIC is installed on the target node, you must use Dedicated Service Tools (DST) to configure disk units on the target node. Follow the instructions here: Adding disk units to an existing auxiliary storage pool.
