The thing could be that from version 8.3 Cisco made some huge changes in the nat functionality. I think you might want to manually review the setup to check. There might be something messed up there.

Have a look at: http://www.cisco.com/en/US/docs/security/asa/asa83/upgrading/migrating.html#wp83968
That might help you.

We decided to revert back to the older IOS. Will revisit this shortly.

That could be the access-lists that are used to match the traffic that is permitted to go through the tunnel or the lists that are used for the nat exempts (no nat) for the traffic going through the tunnel. As said before, I suspect it has to do with the latter.

If possible, the easiest way might be to set up a new site2site VPN using the wizard in ASDM and be done with it.
