  AFaIK the migration utilities were all removed since some V5 release, 
so the actual migration might be easier using the old system.  The 
source members and data members can all be moved easily enough, but the 
conversion features went away with the utilities.  I forget the means to 
move the data to media on the S/36, but the Restore S/36 File (RSTS36F) 
restores the file data to the new system and the Restore S/36 Library 
Members (RSTS36LIBM) to restore the /objects/ into source files QS36SRC 
and QS36PRC and into the data files QS36LOD and QS36SBR.  Many of the 
S/36 library objects will be worthless without the associated CVTS36xxx 
commands however; e.g. without CVTS36QRY, its associated member in 
QS36SBR is just taking up storage.  At the following link are some 
documents for "migration" from the System/36; search on that in the page 
presented here:

  If the new application is done outside of the S/36EE then that would 
probably be best.  Best because that could avoid migration of most 
eveything other than the database data and metadata.  For example, 
migrating the users, libraries, and library contents are not very 
relevant if the new application is not running under the S/36E; all that 
OCL and anything else dependent on S/36-like features would be moot. 
Test and verify the ETL of the data, plus the results under the new 
application, then schedule a cutoff for the final ETL event followed by 
bringing the new application online to the new system.
