Very good question.

We document a $GEMSTONE/bin/postconv script for use in recompiling the 
sort blocks in the 2.4 to 3.3 section of the installation guide[1] and 
after a quick read of the script, there doesn't appear to be any 
2.4-specific operations in the script so it should work for a 3.2 to 3.3 
upgrade as well.

The postconv script arranges to run multiple gems in parallel to do the 
conversion with cache warmers and the whole nine yards, but basic 
operations can be distilled to the following for each SortedCollection 

   | sc sortBlock val cls str val |
   sc := "sortedcollection instance".
   sortBlock := sc sortBlock.
   str := sortBlock _sourceString.
   val := str evaluate.
   sc _sortBlock: val

Now this only works for simple blocks ... if the blocks are more 
complicated then you will have to provide the proper evaluation context 
for the `evaluate` call ... I can help with that if necessary.

The script hasn't been incorporated into GsDevKit_home, but I think it 
would be a good idea[2].
