I’m testing an upgrade from Mautic 4 to Mautic 5, but I noticed that most statistics—especially email and campaign data—are showing “ **no data found** ”, while form data appears to be intact.

I initially struggled with migrating my database to M5 and had to fix some JSON issues and remove all old plugins before proceeding with the upgrade.

Should email and campaign statistics from M4 carry over and remain accessible in M5?

Is there an additional step I might be missing to ensure statistics are properly updated in M5?

No I have not. I am still on 4 for now since I had to put on hold for now. Other thing took priority.

Have the same issue, and can’t solve it.  
It seems that the calculations are made differently between 4 and 5, so they aren’t just considered (my guess, not sure).

But the the dat I normally use to trigger campaigns are working.
