Well.. i tried to find this out..
We actually used this plugin (https://wordpress.org/support/plugin/advanced-custom-fields-migrator) long time back.
But i want rid of such huge data stored in option table for custom fields.
Any suggestions?
Yes right.. but i am seeing some backdated entries on our options table which are custom fields.
may be some previous version of ACF stored this. isn’t it?
O can sse the defination of get_field() function where its trying to get the data from postmeta else usermeta else from options..
