How do I consolidate custom fields?

[Rob Wiskow]

After importing a large number of projects from a redmine instance, I have multiple copies of custom fields that the importer created. Issues are each using only a single version of the field. How can I merge those fields together?

A solution with some effort could be:

• make a backup
• choose one custom field to keep an delete the others including the projects they are used in
• then rename the field to what it is called in the other project(s) and import them one by one

Example:

Project1 uses FieldA
Project2 uses Field_A

• Backup and delete Field_A and Project2
• Rename FieldA to Field_A and import Project2

This could be quite much work if there are many fields and projects involved :(
