Our org created 20k+ "contact" records in custom objects that was later migrated to the proper Contacts object without using Leads for anything. Over about 6 years many custom Contacts fields were created (200+) and now we need to use Leads for web-to-lead forms.
We're a small NPO, so using an app isn't going to work due to cost.
I want to use the Contact object metadata file and the Force.Com IDE to pull over the field customizations done into the Leads metadata file. First, is this a good approach? If so, will surgically copying the
<fields> tag and contents be all we need? What about
<displayedfields> (and others)?
