Prior to applying 8.7 SP1, retain the static IP network configuration by disabling cloud-init network config, which allows netconfig to control the network settings on reboot or not overridden by cloud-init.

Change in appliance as below:
1. Add  the following in /etc/cloud/cloud.cfg file:
network:
config: disabled

Please note that the lines should be added at the end of the file. Otherwise, server will lose its network settings.

2. Rebooted the appliance. Type:
Sudo reboot

3. If the upgrade was already progressed and encountered the network settings wiped out, then this can be resolved by manually configuring the appliance network settings with “configureNetwork.py” script as per KB 000043629:
