Is there any way to merge version history of 2 files with same LID. There are 2 DCRs in my workarea with same lid, I suppose it got created by renaming folder/copying file 3 years back. Both file is having same lid but names are different. The version history of old file is not there in the new file. Now I want to merge version history of the old file to the new file and delete the old file. Is it possible?
