Path of external indexed files

Hello,

i have indexed very very much files on a fileserver with local DT. Now the filestrucure has been moved to another Folder. Everything but the first foldername in the tree is the same, so a simple change of the path would be the best to say DT where the files lie now. But i dont find any way to change the path for indexed files. Is there any chance or do i have to delete all the current indexes and index als the folders angain?

The subfolders have moved from one folder to the other. I dont understand your procedure. The files are on a fileserver in a datacenter, not local. Its not about folders in DT. Its about indexed external folders.
