We already have version 2003 now. I am opening a old ver diagram and trying
to modify it does not have all the features of the new version. That is the
reason I wanted to convert the diagram into 2003 version. So that I can use
all the 2003 version features of Visio.
When you save a drawing in Visio 2003, it is saved as Visio 2003 format. It
is possible to change the default saved format to Visio 2000/2002, but 2003
is the normal default format.
