What is the best practice to manage configuration requiring domain-specific functionality after upgrading to Paris?

Utilizing domain-separated Application Properties is the best practice for managing configuration requiring domain-specific functionality after upgrading to Paris. This approach allows for tailored configurations that cater specifically to the needs of different domains within the application. By leveraging domain separation, you ensure that any changes or settings are localized to a particular domain, thereby preventing any unintended impact on others.

This method enhances the effectiveness of the application by allowing for varied functionality and user experience depending on the domain in question, fostering a more customized and efficient management of configurations. It supports the goal of maintaining specific properties relevant to distinct business contexts, thus streamlining the overall operational efficiency post-upgrade.

In contrast to this approach, global configuration options would apply changes universally across all domains, which could disrupt functionality and lead to complications. Configuring properties through a third-party app may introduce dependencies or compatibility issues that could arise during or after the upgrade. Keeping all settings as default would negate the potential benefits of a customized experience and may not address specific functional requirements unique to different domains.
