SNgine SEO

I had recently just migrated from WoWonder to SNgine.

My current organic site traffic is still coming from the indexed content from my old WoWonder sitemaps, but they are now hitting 404 pages.

Since SNgine does not use sitemaps, should I delete the sitemaps from my WoWonder and have Google reindex my new posts from SNgine?

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;

I have not imported my WoWonder posts into SNgine yet.

Please clarify I will need to do this first before setting up the redirect. 

I don't think you can redirect something that doesn't exist so I suggest you import your post first. Or if you rewrite the post. You redirect the old post to the new post.
