  You can rerun the createRemoteMigrJar
  script with -includeJava false option.

  ****************************************************************
  Remote migration jars can be generated either to include a
  Java runtime (-includeJava true on WAS 9.0 or -skipJava false
  on WAS 8.5.5) which creates a jar that can only run on the
  same OS and architecture as the system used to generate it, or
  to include no Java runtime at all, which creates an OS
  agnostic jar capable of using a Java runtime on the target
  system. If Java is included, WASPreUpgrade within the jar runs
  several environment checks to ensure the OS and architecture
  match what it is expecting.
  Among these checks is to verify that the address width of the
  architecture is 64-bit. It does this on Linux by issuing
  ´uname -p´ and looking for a string with "64" in it. Both
  x86_64 and ppc64le match, but s390x doesn't despite being a 64
  bit architecture.
  

Problem conclusion

• The remote migration WASPreUpgrade script was updated to
  accept s390x as a 64 bit processor architecture.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.5.1 and 8.5.5.17.  Please refer to the Recommended
  Updates
  page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• Adjust the WASPreUpgrade.sh script to replace the line reading
  "*64*) ;;" with "*s390x*) ;;".
