How to boot netapp 7 mode with privious version

[NetappFAS2220]

 Hi,

My Netapp device boot with latest upgraded version every time 8.2.3P2 & it works fine but my 7-character key not working. it need 28 character key. I upgraded my netapp device 8.1 to 8.2 last year. when i see in my netapp system "Version"  then it show me both os available in my netapp. ( Screenshot attached below).  

What i can do to use my netapp? Can i downgrade 8.2 to 8.1 ( Please help me for how to process) or 

Version and Mode	License Key Format
Data ONTAP 8.0/8.1 7-Mode	7-character, all uppercase alpha (example: ABCDEFG)
Clustered Data ONTAP 8.0/8.1	14-character, all uppercase alpha (example: ABCDEFGHJKLMNP)
Data ONTAP 8.2 (both modes) and 8.3	28-character, all uppercase alpha (example: ABCDEFGHJKLMNPQRSTUVWXYZABCD)

Agreed. We can just get it for you in Support. It also might be on the Support site or ActiveIQ page under your installed systems.
