I just did this yesterday, so here's my experience. If you have a simple single-server installation with no custom LDAP DIT modifications, you should find "yum upgrade" does the right thing.

If you do have DIT mods, you should ask yourself why they are there and whether the data will still be accessible after the ACLs are changed. In my case, I had Postfix using a LDAP hash and mail delivery stopped working (although the domain data was still there just fine).

Note that the ACLs will propagate from the 4.1 server to your 3.0 if they are replicated. To be safe, back up all replicas (snapshot or whatnot) before the first upgrade and if you decide to restore any of them, be sure everything is shut down and restore all of them to avoid 4.x schema contaminating 3.0 as they come up.
