yes this is possible. also note that when you update from a plone with
python 2.6
to a version with python 2.7 this is the most painless way

having said this: try to keep each step separate, don't do too much at
one time,
if you run into errors you will have an easier time if you know in
what step exactly
the error occurs

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.

1) Don’t drive species to extinction

2) Don’t destroy a habitat that species rely on.

3) Don’t change the climate in ways that will result in the above.
