Should You Delete the Old Sitemap?
Not immediately. Simply deleting the sitemap won't inform Google where to find your new content. Instead, you need to handle the transition carefully using redirects.
The best way to preserve your organic traffic is to redirect the old URLs to equivalent or relevant pages in Sngine.
Use 301 redirects (permanent redirects) to guide both users and search engines to the correct locations.
301 redirects pass most of the SEO authority from your old pages to the new ones.
If you still have access to your old WoWonder URL structure, create a mapping:
Old WoWonder URLs → New Sngine URLs.
Add 301 redirects in your server configuration:
For Apache (.htaccess):
Redirect 301 /old-wowonder-post-url https://yoursite.com/new-sngine-post-url
For Nginx:
rewrite ^/old-wowonder-post-url$ https://yoursite.com/new-sngine-post-url permanent;
