Why would they want to maintain the JCL?

Talk to them. What they REALLY want is to have their current batch
processing performed in a client/server environment.

The best approach to this is to analyse the FUNCTIONALITY of their batch
processing. (This requires the input of at least one knowledgeable
human...).

Once the batch functionality has been determined, it is possible to write
windows scripts that make it happen. Windows Script Hosting is excellent for
this and for many years I never used it, considering it was some esoteric MS
technology. It isn't. It is a very useful equivalent to JCL on a PC. (Unix
scripts could do the same in that environment).

Sometimes people think they know what they want,because that is the extent
of their experience. Find out what is really needed and wanted, then
implement that, using the tools of a PC environment.

A JCL "converter" might be a possible approach, but it is not one I would
personally favour.

Get them to realise that this is a huge opportunity to review what happens
in their batch processing and possibly improve it. The action of analysing
the functionality of their current batch processing is a valuable one and
will drive out opportunities for streamlining it in the new evironment.
