Setting up multiple support portals

Hello,

I'm exploring how we can migrate all of our support options into Zendesk.

We currently have an external public-facing customer support portal in Zendesk (where customers can get support from team members) and two internal private support portals in Jira.

I want to migrate those (2) Jira support portals, that are for internal team members only, to Zendesk.

One support portal where employees can report IT-related issues (password reset, new device needed, etc.) and one where employees can report product-related issues (bug, issue with a part of the platform, etc.).

If anyone is using Zendesk in a similar fashion, please let me know how to best set this up.
