Verify the upgrade on IBM i

After you have verified the installation, start the IBM MQ subsystem, check the queue managers, and take a fresh media recovery checkpoint.

To verify that we have migrated to the latest version IBM MQ for IBM i, successfully:

Make QMQMADM either the primary or a secondary group profile for the user profile. To do so, issue one of the following commands:
```
CHGUSRPRF USRPRF( YOUR PROFILE ) GRPPRF(QMQMADM)
CHGUSRPRF USRPRF( YOUR PROFILE ) SUPGRPPRF(QMQMADM)
```
Start the IBM MQ subsystem with the command:
```
STRSBS SBSD(QMQM/QMQM)
```
(If it is already running, you get error message CPF1010 which we can safely ignore).
Check that your queue managers are accessible by issuing the command:
```
WRKMQM
```
Use option 14 against each queue manager to start it.

Use option 5 against each queue manager to check its attributes.
We can use the other options to check your queue manager objects. For example, check your queues using option 18, check your channels using option 20, and so on.
Take a fresh media recovery checkpoint, using the following command:
```
RCDMQMIMG OBJ(*ALL) OBJTYPE(*ALL) MQMNAME( QMGRNAME ) DSPJRNDTA(*YES)
```
Where QMGRNAME is the name of the queue manager.
