I would try each one separately (new,current,history) and use the criteria/range button to find the job you are looking for

JC - Help - Help Topics - Index Tab - choose Move Overview.  My guess is that year-end procedures where to move jobs and transactions to an archive data file.  You'd have to find the archive file.  It may be in a much older version of Sage and not useable now, unless it's been upgraded each time you upgraded to newer versions.
