change all the asp to html
Explain what you mean by that. Do the files contain pure HTML code or are they ASP scripts with ASP code too?
You should keep the same URLs and then use mod_rewrite to rewrite requests for those URLs to whatever the new internal filename is called. The user need never see what the new files are called.
