I'm not sure if our errors were exactly the same, but migration failed for us as well. I only cared about the processes so I exported them all on the old version. We started as a fresh install then imported the process archives.
Els Uyttenhove..., I'm in the same boat as you. Got the following error while installing ES on Linux.
I solved it by deinstalling everything from the old version (7.2.2) and I did a new install for the Livecycle ES 8.2 software without any problem. So upgrading from 7.2.2 to 8.2 didn't work for me, but a new install has no problems.
For me it was possible to do so, because we only use forms and reader extensions, and I lost no data, but I think this isn't a solution for everyone......
Els.., Thanks for getting back to me. My problem is solved. Here is the list of things I did to fix it:
1) Delete main Livecycle directory on Linux
2) Manually uninstall all the ear files from Websphere admin console
3) Perform a fresh install
4) Carefully use the port numbers. (SOAP port is pulled from Deployment Manager and Appserver's ORB port is used for JNDI).
