Support › General › What to do with old fields after running extension ACT to Metabox migration?
Three months ago I have to the migration from ACF to Metabox. I have read on a post that old fields still exist in the database. What do I have to to check this and remove?
WordPress itself does not support an option to delete old post meta. If you are familiar with SQL skills, you can follow the ACF guide to know how to delete the old custom fields
FYI, ACF custom fields will have meta key underscore_fieldID like this: _textfield
