Is there a way to exclude robots during the OC install 'Verify Probes' process to shorten the install/upgrade time?

Issue/Introduction

We have approx 700 robots that report to the Primary hub and noted that the OC installer takes long time (4+ hours) before displaying the Verified Probes menu.

The oc.log shows that a  probe_list callback is performed against all robots that belong to the Primary hub for each probe in the 'Verify Probes' list

Example:

/uimdomain/primaryhub/robot1/ did not respond to probe_list (name=automated_deployment_engine): (4)

Is there a way to exclude robots during the OC installer 'Verify Probes' process to shorten the install/upgrade time?

Environment

Any version of OC 20.4 Install or Upgrade

Resolution

The recommended option is to temporarily move all robots except for the CABI and OC to secondary hub that is configured with the same origin. Robots can be moved back to the Primary hub after OC install completes.
