I think you’re trying to communicate information without using terminologies.
Are you actually talking about two different database connections or are you talking about Groups in Zammad?
Different database connections are not supported in Zammad. Please describe what you’re trying to achieve and try to use Zammad terminology while doing it. Otherwise it will be a pain for both sides to understand and help. The admin documentation might also be a good starting point to start reading: https://admin-docs.zammad.org
Unfortunately your recent posts where all rather vague.
