Northfell Veterinary Holdings runs a separate production org for each of its twelve regional hospital groups and wants to deploy the same base agent configuration to all twelve consistently, then track each org's customizations over time. Which deployment approach best fits this requirement?

A scenario with a shared base configuration that needs to reach many orgs consistently, while still letting each org diverge afterward, calls for packaging the agent's metadata so it can be deployed repeatably rather than recreated by hand. Tracking each org's later customizations against that shared baseline is exactly the point of building from a common package: it gives the specialist a reliable starting point everywhere and a clear way to see where each region has since diverged. Manually rebuilding the agent from scratch in each org discards the benefit of a shared baseline entirely and multiplies the chance of configuration drift and human error across twelve separate builds. Deploying in only one org and asking the other eleven teams to copy settings from screenshots is unreliable, unrepeatable, and effectively abandons any deployment discipline. Skipping Testing Center in the regional orgs is also unsound, because each org has its own data, users, and potentially its own customizations, so a pass in one org's tests does not guarantee correct behavior in another org even when they started from the same package.
