The easiest solution is Boomerang by Everest Software.
Without that tool, you could look at creating datasources, pathcodes, OCMs & OMW Rules that would move object code from instance-1-pathcode to instance-2-pathcode.
Without more information, the money spent on 2 Site Limited licenses (one for each instance) could be well worth it.
have a question on copying custom objects across 2 JDE instances (so 2 different deployment servers and its XE so there reportedly no .ZIP option).
could you help?
