The only problem occurs when reverting from a C-series firmware back to 
a B-series.  Once you have moved to C, you can't go back to B.  But 
within the C series, you can upgrage/downgrade at will.

Note that no B-series firmware revision supports suspend/resume at all.

You can save the manufacturing data to a file on USB key with the command

 ok save-mfg-data

That will create a file with an 8.3 name consisting of the last 11 
digits of your machine's serial number, containing an image of the 
manufacturing data.  Note, however, that there is currently no canned 
command to restore the contents of that file to FLASH.  So far doing so 
has just not been a priority.

The one time that someone actually used save-mfg-data, they shortly 
thereafter loaned their USB key out to someone who overwrote it.  
Murphy's Law strikes again.
