Update ConTeXt 2004-12-06 for teTeX 2.99.4-beta: map files

Hi all,
I have a running tetex-2.99.4-beta. Now I would like to update ConTeXt
to version 2004-12-06.
After comparing directory structures I see there is difference:

1. In ConTeXt all map files are in fonts/map/pdftex/context/*.map
2. In teTeX amm map files are in fonts/map/dvips/context/*.map

So my question is how I could update ConTeXt safely ? Which directory
structure I have to follow ? teTeX will continue to work if map files
installed in ConTeXt's structure ?

Thank you in advance,

Regards,
