Remove the source GAD and UR pairs after starting operations on the target GAD and UR pairs.

Delete the source UR pair.
Command example:
```
pairsplit -g UR00 -S -IH01
```
Delete the source UR delta resync pair.
Command example:
```
pairsplit -g UR01 -S -IH02
```
Delete the source GAD pair while letting the virtual information for the P-VOL remain.
Command example:
```
pairsplit -g HA00 -S -IH01
```
Delete the temporary GAD pair used for migration while letting the virtual information for the S-VOL remain.
Command example:
```
pairsplit -g HA20 -R -IH11
```
Delete the remote connections between the storage systems of the source UR pair, between the storage systems of the source GAD pair, and between the storage systems of the temporary GAD pair used for migration.
Run the following commands on the server that connects to the storage system at the source GAD primary site:
1. Delete the remote connections to the source GAD secondary site, to the source UR secondary site, and to the secondary site of the temporary GAD pair used for migration.
```
raidcom delete rcu -cu_free 422222 M800 0 -IH01
```
```
raidcom delete rcu -cu_free 433333 M800 1 -IH01
```
```
raidcom delete rcu -cu_free 844444 M800 3 -IH01
```
2. Verify that the processing for the asynchronous commands normally ended.
```
raidcom get command_status -IH01
```
Run the following commands on the server that connects to the storage system at the source GAD secondary site:
1. Delete the remote connections to the source GAD primary site and to the source UR secondary site.
```
raidcom delete rcu -cu_free 411111 M800 0 -IH02
```
```
raidcom delete rcu -cu_free 433333 M800 2 -IH02
```
2. Verify that the processing for the asynchronous commands normally ended.
```
raidcom get command_status -IH02
```
Run the following commands on the server that connects to the storage system at the target GAD primary site:
1. Delete the remote connection to the source GAD primary site.
```
raidcom delete rcu -cu_free 411111 M800 1 -IH11
```
2. Verify that the processing for the asynchronous commands normally ended.
```
raidcom get command_status -IH11
```
Stop the CCI instances for the deleted pairs. The following procedure is for Windows.
1. On the server that connects to the storage system at the source GAD primary site, stop CCI instance 01.
```
horcmshutdown 01
```
2. On the server that connects to the storage system at the source GAD secondary site, stop CCI instance 02.
```
horcmshutdown 02
```
3. On the server that connects to the storage system at the source UR secondary site, stop CCI instance 03.
```
horcmshutdown 03
```
4. On the server that connects to the storage system at the target GAD primary site, stop CCI instance 11.
```
horcmshutdown 11
```
Delete the information of the temporary GAD pair used for migration from the configuration definition file for the CCI instance that was shared by the target GAD pair, the target UR pair, and the temporary GAD pair used for migration.
Restart the CCI instance on the server that connects to the storage system at the target GAD primary site. The following procedure is for Windows.
```
horcmstart 11
```
Remove the storage systems in the source environment as necessary.
