Import file

Hi, I need some advice. I have a dreamhost acc.
In order to improve my new website, I am trying to import a file that weighs 33 MB, using wordpress system, but dreamhost allows only to import 7 MB. How can I do to get my limit expanded?

What type of file is it and is there any reason you can’t use FTP or SSH?

Type of file: is a . xml 36MB containing a wordpress software that allows some WordPress installations, but the downloading limitations or handling capacity of the Dreamhost hosting for the import of an external file into my system is 7MB.
The wordpress file contains all the posts, comments, categories, tags, etc… of one website (already hosted in Dreamhost in my acc) that I want to download in order to save work in the development of the new website.
