I have a document library with a content type (Programs, Topics, Label1, Label2, Label3 as columns) and I want to replace it with new content type (Program1, Topic1, Label11, Label21, Label31) due to some reasons. I have hundreds of documents that are currently
using the first content type .
The question is- is there any way to replace the first content type with the second content type and map values of Programs to Program1, Topics to Topic1..so on.. and complately delete the first content type with out actually modifying the modified
time.
