How do I confirm, if partitions on my Aruba Instant Access Points are running the latest version?

Aruba Instant Access Points come with two partitions.  Primary and Backup partitions.  Currently running partition is called as Primary partition. Whenever, IAP is upgraded or downgraded to an other InstantOS version, this would copied into Backup partition. 

Using the CLI command, one can look at both the partitions and the Instant version within them:

"show image version"

Primary Partition shows that this IAP is running 4.2.2.1.  Lets see if that is the case, by issuing the command "show version"
