Migrating to new server but question about IP assignment

[dchamb]

I am migrating my old unRaid system to a new Intel hardware. My old system is recognized as 192.168.1.99. Do I need to have my router set to match that IP address to the MAC address of the new hardware before I boot it up, or is the IP address set up on the flash boot drive as a static address?

I would just boot it up and see what ip is issued via DHCP.  After that, go to the router and assign it a static address.

What I need is for the new server to pickup the same IP address. Maybe I should change it in the router first. The old hardware won't be running when I power up the new one.
