The steps and examples in this section provide commands you can use to determine the configuration of your source system, including details about the zones that you plan to lift and shift. After the lift and shift process, the configuration information can also serve as a reference when you verify the migrated zones on the target system.
As you perform this procedure, take into account the state of your source system and adjust and omit steps as needed.
Capturing the commands and output provides a means to refer back to the data that is collected.
There are a variety of methods to capture output. You can run the script(1M) command to make a record of a terminal session, or use a terminal window with command and output collection capabilities.
Example:
root@SourceGlobal# script /tmp/source_zones_output.txt
Note – When you want to stop capturing output, type Ctr-D.

In this example, the ASM raw disks are on slice 0 of disks 10 and 11 (as numbered by the format utility).
The capacities in GB can be extracted from the disk partition table using the following scripts.
For this example, each ASM raw disk is approximately 199 GB.

The disk capacity information is used to configure the target system storage that is needed for the migration. See Prepare the Target System.
The total amount of used storage is used to calculate the amount of space needed in the shared storage in Prepare the Shared Storage.
This table lists the disk calculation for this example.
