vbseo Sitmap uninstall before installing vbseo?

I have vbseo Sitemaps installed already so do i replace the .htaccess file for vbSEO Sitemaps with this new .htaccess file or cut and paste it's contents within the current .htacess file?

Thanks!

The .htaccess that comes with vBSEO should already contain the line for Sitemap, so you can just overwrite your old .htaccess if you had no other custom entries.

thanks!
