Pix to ASA migration

[timpacalypse () yahoo com]

I am moving from a PIX 6.3(3) to an ASA 5520.  I thought it would be as easy as copying the configuration from the PIX 
into the ASA but apparently not.  The interface configuration syntax was a little off but easy enough fix.  Everything 
else seemed to go through fine.  

So I plug it in and it's angry.  It seems like DNS doesn't work.  

So I went back and did a little reading.  I think that when I was configuring the policy map for the IPS that I may 
have over written the default inspection policy map (fixup dns, fixup skinny, etc).  

My question is, if none of fixup protocols are set will that prevent me from getting out to the internet?  My 
understanding is that the appliance just inspects the traffic, I thought that if I set No fixup that it just wouldn't 
inspect it.
