Upgrading SAP R3 ALEIDoc and RFCBAPI to version 42

I’m working on a project to upgrade our Enterprise SAP R/3 adapter software from 4.1.1 to 4.2 on a Solaris server. Our enterprise server broker in version 5.0 on a Solaris server. I attempted the upgrade in our development environment, but the adapters are not able to start up. Does anyone have any experience doing this? Does anyone have any information on the new adapter settings. I’ve checked the webMethods documentation and they don’t identify or explain the new fields on the adapter.
