Unifi Scenario possible?

Hello, any helpful advice that has more experience using Unifi products.

I would like to upgrade our Cisco 1 GBs switch to a 2.5 from Unifi to improve our LAN speed.
Our Server and Fortigate have 10 GBS SFPs that is not in use.
Our Cabling is CAT6


  • Fortigate 100F
  • Switch Pro Aggregation
  • Switch Enterprise 48 PoE (3)
  • Dell Server (ESXI)

They should all work together.
