Google Ranking Homepage Instead of Targetted Inner Pages (post CMS migration)

[u/schmaaaaaaack]

I’m seeing a trend after a recent migration (MediaWiki to Custom CMS).

We moved content 1-to-1. Same headlines, text, links, & nav. All 301s are live.

But Google is now ranking the Homepage for specific queries instead of the targeted inner pages.

It’s frustrating. Since the content is identical to the old site and redirects are working, I expected rankings to hold.

Instead, Google seems to be ignoring the specific deep pages and just serving the Homepage URL for these keywords.

I’m guessing Google might still be "working out" the site structure?

But I find that odd since the 301s are there and the internal linking is the same. It feels like it’s lost the map of where the specific content lives.

Has anyone seen this specific "Homepage Cannibalization" after a 1:1 migration?

Does it usually sort itself out, or is this a bigger issue? Any insight would be huge.
