as per the guide lines :

upgrade to Release 8.2.16x or 8.3.x and then upgrade to Release 8.5.161.0.

Also read the each release guide lines and understand the caviets and take backup of configuration each upgrade out of the box for safety.

Also AP Matrix also.

Upgrade to an interim version, 8.2.12X.X, first before jumping to 8.5.X.X.

@Leo Laohoo , thanks for your reply. But @balaji.bandi advised to upgrade to 8.2.16x first, can you please help to verify? Thanks.

@balaji.bandi is correct.  

Me bad.  It is 8.2.16X.X first and then 8.5.X.X.
