How to connect new fortiswitches to existing fg61e

[gcraenen]

Hi,

I'm running a FG61E on fortios 6.4.4 with all LAN ports in the hardware switch and being used. I bought a couple fortiswitches to replace the old switches in my network. I can see the fortilink page which states that I don't have physical ports available. That's right, there all being used. In 6.2.x I could just state to use the existing hardware switch with ports.

In 6.4.4 can I just connect the new fortiswitches to the FG existing netwrk connections instead if the to be removed switches and are they then going to be recognised? Or do I have to completely reconfigure the FG?
