Things didn’t go especially smooth but I now have all the NFS and virtual host servers upgraded.  I’ve been testing on one machine prior to upgrading the rest and this appears to fix the NFS synchronization bugs that have plagued us since 16.04 LTS (the last two years).

     One machine, the upgrade process removed a bunch of necessary packages like the RAID software and the EFI firmware for virtual hosts.  I’m still testing everything but as far as I know it’s all back together now.
