Just launched a redesign. Changed URL structure using redirects.

Was looking forward to comparing KPIs of original versions of pages with new improved versions. But since the URLs have changed I can't compare new URL to the old URL.

I'm not finding anything online to remedy this. Anyone dealt with this during a site migration where you're changing the URLs (not the domain)?

At some point I'd like to compare post launch with pre launch to see changes in bounce rates, conversions, etc.

Thanks!
