Our current CR is on v29 and need to update to v31.  We’ve already downloaded the necessary files for the update.  This would be my first time updating the CR and wanted some guidance on how to properly update.  There are currently 20 VDIs, 1 and 2 and test, 3-10 are production, and 11-20 are extra VDIs on standby just in case we need some additional capacity.  I appreciate you all in advance.
