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.
