Hi,
please have a look at the minimal example at the bottom.  I am
typesetting theorems and lemmata which are numbered consecutively
within chapters in a book.  I used the same code for a document
written in mkii, and I thought I could just reuse it in mkiv.
Obviously, there is something I am missing.  Question: How do I get
the same output when compiling the following code with 'context' as
when compiled with 'texexec'.
When compiled with 'context', the chapter number is missing in the
numbering of theorems. Lemmas are not numbered at all.

\setupenumerations
   [title=yes,
   style=normal,
   list=all,
   before={\blank[big]},
   after={\blank[big]},
   location=serried,
Change “location=serried” to “alternative=serried”.
...
width=broad,
   distance=0.5em,
   headstyle=bold,
   titlestyle=bold,
   way=bychapter,
   conversion=numbers]
You have to change “conversion” to “numberconversion” but this isn’t
necessary because numbers are the default conversion format.
To have chapter numbers as part of the counter add “prefix=yes”.
...
\defineenumeration
   [theorem]
   [text=Theorem, listtext={Theorem }]
\defineenumeration
   [lemma]
   [text=Lemma, listtext={Lemma }, number=theorem]
To use the counter of another enumeration use “counter=theorem”, not “name=theorem”.

Thanks Wolfgang for the quick answer.  I changed my code accordingly.
The "prefix=yes" option, though, does not entirely do as I expect it.
It adds the chapter+section number as a prefix to each theorem (and
lemma).  As I have "way=bychapter" in my options, though, it doesn't
reset after a new section started (which is what I want!). The effect
is odd as you can see in the minimal example.
I only want to have the chapter number as a prefix. It's probably
simple? difficult?

To answer my own question, adding

    way=bychapter,
    prefixsegments=chapter,

did the job!
