[cvsnt] how to update an export ?

[Arthur]

HEllo,

I would like to update files on a prod computer that come from CVS.
On the prod computer, there is a directory that is used to store files of a
web server.
This directory has been created with a cvs export command from a module from
the repository.
Now, I would like to update theses files with the changed files from the
same module of the same repository.
In fact, it is an update of the export.

How could I do that ?

When I use cvs export twice, it says that files already exists.

Thank you.
