I looked for the scripts I wrote for our conversion years ago, and couldn't find 'em, but other comments made have sparked a few additional memories:
For printing, we wrote scripts to send stuff to printers directly to port 9100, rather than use the OS-based printer interface. This let us customize it a bit more for such things as print job archiving and form overlays, with the benefit of REALLY understanding the entire printing process. For user ids, we had a script that took the password and secure password files (sorry, been too long, don't recall their names!), stripped out everything but user accounts, put in new shell paths (bash vs. ksh), then inserted them into the linux files. Worked very well. Our application had a batch system built it, using the application from Fitzgerald and Long. When we migrated to RH, we rewrote most of it to use "at". Had a few hiccups when we went live, but got them straightened out. One side benefit was the relative ease in developing and testing DR recovery scripts. We were able to do all development and testing of the processes on a desktop machine. In testing at the recovery facility, we had a couple hiccups (had more to do with the equipment/networking at the site, which we had to adjust for), but we were able to complete the DR test, then wiped the recovery system, and did a complete recovery again; all in eight hours.

I would think if you are going intel to intel, and your directory structure hasn't changed, you should be ok without having to recompile, although, to be safe I'd do it. > 3.

Some of the packages it installs are not current and we have to download, compile and install from source (vs using yum). The biggest gotcha, and it's not a Redhat specific, was when we recreated the users, we had to make sure their UID/GID were the same as from the previous system, otherwise the file ownership and group ownership would not be the same. > 7.
