SharePoint 2013: InfoPath Form value update in old forms

Question

Hello Experts,
I have a SP 2013 site with InfoPath form published onto the list, few fields from this form is promoted to be saved as list colum value. Everything works as expected.
So far, we have approx 2000+ form saved in this list. With new change request, I need to promote another field (say XYZ) from existing form as list column. This XYZ field is present in the form from starting and all 2000 forms contains value in this
field.
My question - When new forms are saved, this XYZ value can be saved in list item but is there any way I can pull values from XYZ field from existing 2000 forms to be saved onto list item.
Any help is appreciated.
Regards,
Ankur

Yes there is.
You can use "Relink Documents" from your Current View dropdown in the Ribbon. But don't use this if you have any workflows connected to the library, they WILL RUN.
Instead, you can render the forms in "Open with Explorer" view. In the Ribbon, under the Library Tools, Library tab, in the Connect & Export section, click on
Open with Explorer. As the files render in the Explorer window, you will see the icons next to the file names change to the InfoPath icon. Wait for them all to change. If you have a lot of files, you can scroll down to expose the ones that have not
changed yet. When all the icons have rendered, shut the Explorer window and refresh your view, you will see the promoted columns contain the data that was in the form.
