Move content from field to field collection I'm working on a site where a current content type has six image fields, six title fields &amp; six content fields. One field from each (one image, one title &amp; one content) all make up one group, so in total there are six groups of these.

Is it possible to move these into a field collection? I just think it'd be tidier, make more sense &amp; make it easier to maintain.

Also if this is possible, not only how do I do it but is it even wise to move content from a 'normal' field to a field collection like this?
You can do it with 3 step


In your content type, creat new field collection
Write one module, use function hook_node_presave(). In this function, you can copy data from old fields to new field collections.
Go to page admin/content. Select your content type. Select all node. In tab UPDATE OPTIONS chose Publish selected content and submit. This action to do run code your module write in step 2.
