Replacing LAN STACK

Hello.  Hoping I can get some advice on what I'm about to do.  I currently have four 6248 switches in a stack.  The back side of two of the switches have a 10gig module uplinking the stack to two 10GIG switches which serve my vmware/storage environment.  

I have purchase four new switches (N3248TE-ON).  They do not have rear modules, however they do have four 10GIG ports on the right side of the front.  

Can I use these front 10gig ports as the uplinks to my 10GIG network?  If so, I suppose I would configure them to be trunks?

Any helpful suggestions or thoughts would be appreciated.

Thanks,

GJ
