Thanks. I tried it and the number of pages indexed were 1,004, which is less than the previous indexing. So I have to believe it worked.
Looks good in /sitemap.xml, however I am unable to find /sitemap_generator/data/urllist.txt or /sitemap_generator/data/sitemap1.html. I just converted to 2.0. Is there some setting I'm missing to create these files?
