I am wondering the pitfalls of running 32 bit applications on 64 bit Linux.

We are looking at upgrading a large enterprise system.   It would be  
very helpful if we could upgrade the operating system first, because  
then we can upgrade the application in place and carry over all of our  
settings and data more easily.   The old version is a 32 bit  
application, the new one is a 64 bit application.   If we upgrade the  
hardware and operating system first, this is better, since it is due a  
hardware upgrade anyway, and we are looking at maybe moving it to a  
new data center.   We would like to run this way for a while, then do  
the upgrade, since it is a large project to upgrade this mess.  Where  
is this going to bite us?
