I appreciate your response.
Unfortunately I did not understand exactly what to do and what to migrate in mudandaças should do manually indicated in the table of actions and filters. The text says that it is easy to migrate, and indicates http://www.advancedcustomfields.com/docs/tutorials/creating-a-new-field-type/ this link to learn more, but does not work.
So I found it easier to remove the 15 fields created and recreates them on the same site. There was no reference to them in functions.php and I believed that the simple removal of the fields via plugin erase the references in the database.
Maybe relamente easy for those who are accustomed to the plugin and meet the English language perfectly, my English is not fluent.
Thanks for the help!
