Here are some things to keep in mind when you do your account upgrade:
1. The plan you're upgrading from. If you upgrade from a BASIC to a PRO PLUS plan on January 21st, you will be able to see data from conferences (Conference details tab) as far back as January 15th. After this point, you will have PRO PLUS level retention (i.e. on January 29th, you will still be able to see conferences from January 15th).
2. Aggregated metrics history (Service metrics tab) is longer than that of individual conference data (Conference details tab).
