So what do you recommend ? ::
In your case it wont work since Institution is not a attribute of an Individual but of an education.
Here is an example how to copy a custom tag representing the employer to the data field "Employer".
Use copy column while the entire grid is selected and the paste it in the destination column.
On the other hand, from one version to another, new fields has been defined as standard ones, by the system.
For example, today, there is a standard field called "Institution Name" under the "Education" tag.
Long before this "Education" tag has appeared, there were users who had defined such a field under one of their Custom Tags.
Generally speaking, what's needed today, is a tool which would make possible the removal of the content of a field defined under Customs Tags, to the parallel one defined under a standard TAG of the program. (something which shall scan the entire database, removing data from a given field A to another given field B). After the action takes place, the field "A" should become empty (and ready for being deleted from the database).
