XF 1.5 htaccess redirects + friendly URLs (SEO question)

[Peace]

I'm working on migrating our vB4 forum to xF. We're retaining the content IDs, so I figured I could write some simple htaccess redirects to make sure all of our old content gets redirected.

My concern is the friendly URLs. My htaccess rewrites only pay attention to content ID, for example:

http://example.com/showthread.php?46409-test-thread

->

https://example.com/threads/test-thread.46409

But the rewrite would simply see

http://example.com/showthread.php?46409

->

https://example.com/threads/46409

So the friendly URLs are lost Does this mean Google won't see the xF friendly URLs either, and thus an SEO problem? Or will it figure out the redirect by itself, because xF automatically adds the friendly URL text if you access with ID only.

This. You'll end up at the correct thread.
