vSphere 5.0 upgrade with new hosts

Hi,

I wanted to give my scneraio here for some advice.  I currently have a vSphere 4.1 Ent. setup with 2 hosts and a SAN.  Everything has been working great.  We are wanting to upgrade to vSphere Esxi 5.0 soon.  I have actually already upgraded vCenter to 5.0 along with all modules.  My current hosts are 4 years old so I am going to replace them with 2 new hosts with esxi 5.0.  One of my questions is...at this this point can I simply replace my 2 old hosts and replace with the new ones?  I should already be good with my licensing but my concern is the networking side of things.  If I simply replace can I just go into vCenter and reconfigure the networking for these hosts or do I need to pre-configure the host before implementation?  My 2 new hosts will have 8 NICs and my current ones only have 6 NICs.  I thought maybe I could team my production network with 4 NICs versus 2.  Any thoughts on this is appreciated.  We are a small biz so I want to keep as simple as possible.  Just not sure how vCenter will recognize two replaced hosts...
