I am looking for guidance on converting RACF to ACF2. Has anyone done this before? How deep did you test before you converted your production environment?
If yor system is about to become a new ACF2 user, i'd suggest talking with CA. They have been thru this multiple times and will have material that you can use for planning and implementation.
For what it's worth, transitioning from one to the other, you can set the new one in some sort of "warn" mode initially to show up problems without preventing actual production....
