Transferring from the main appliance

Follow this procedure to transfer queue managers and associated data from your existing main appliance.

About this task

This procedure uses the following terminology:

Main appliance - the appliance located in your main data center that runs the primary instances of the queue managers.
Recovery appliance - the appliance in your back up data center that has secondary instances of the queue managers.

To prepare your main appliance to transfer queue managers to a new, replacement appliance, you stop all the queue managers on the appliance, and run the secondary instances as primaries on your recovery appliance. You then delete the disaster recovery pairing between the two appliances.

The main appliance now has no active queue managers, you can disconnect it and power it down.

Procedure

On the main appliance, complete the following steps:
1. Enter MQ administration mode by typing mqcli on the command line.
2. Stop the queue manager that you want to work with:
```
endmqm queue_manager_name
```
3. Make the queue manager the secondary instance:
```
makedrsecondary queue_manager_name
```
On your recovery appliance, complete the following steps:
1. Enter MQ administration mode by typing mqcli on the command line.
2. Make the queue manager the primary instance:
```
makedrprimary queue_manager_name
```
3. Start the queue manager and check that all is working as expected:
```
strmqm queue_manager_name
```
4. Stop the queue manager:
```
endmqm queue_manager_name
```
5. Remove the queue manager from the disaster recovery configuration:
```
dltdrprimary -m queue_manager_name
```
6. Start the queue manager to ensure continuity of service. It is now operating outside of disaster recovery.
7. Repeat these steps for each queue manager.
After you have transferred all your queue managers from the main appliance, you can disconnect it from the network and power it down.
