InsightIQ 5.0 to 5.1 Fails.

Attempting to upgrade our VM which is known as "Simple" (instead of Scaled) deployment fails.   From the /tmp directory, running the upgrade-iiq.sh script to upgrade starts the pre-check, but it fails and stops.  Displaying the logs using showupg -s and -l show "There are 4 unhealthy pods." "Pre-Check pod status failed", and "[ERROR] [PRECHECK] Failed to run precheck, please run showupg --log".   This is using the Administrator account.  In the iiq-510-install.pdf document on pages 26-27, the examples are using the root account.  Don't know if that works for our Simple deployment on a VM or not.  The 5.1 upgrade came out on May 31 and contains fixes that we need.    Any advice?    I've tried performing this after a clean shutdown and power up of the appliance.
