Hi @seanpre
Yes, if you re-create the fields with the same names, ACF should read in the dta as per usual.
I belive v2 used custom tables for the fields. It is neeccessay that this upgrade from v2 to v4 be done in steps from v2 to oldest v2, then to youngest v3, then to oldest v3, then to any v4.
This I’m guessing is no longer possible as the update has already taken place.
Please check your database and see if the data of your value still exist in the postmeta table
