This is slightly suboptimal at the moment.

My suggestion would be the following:
- fetch the latest minimals for 64-bit linux
- remove texmf-context and replace it with the one from your old
machine (alternatively you could fetch that version of ConTeXt from
GIT)
- check which version of LuaTeX you have on the old 32-bit box (it's
probably beta-0.79.1)
- fetch that version from SVN from
    http://svn.contextgarden.net/suite-bin/tex/x86_64-linux
  (if it's that version, just checkout r197)
- you might need to replace mtxrun from the old version (or maybe I
forgot another thing or two)

Everything else should keep working unless some font names changed in
the meantime.

Alternatively start with your old 32-bit tree and just add the
texmf-linux-64 tree from the new installation to it (of course make
sure to replace luatex and potentially other scripts in that tree).
