Of course not. Why are you leaving the -2 file in the same folder as the file with the same name and then trying to name them the same name.. You can not do this rename using the Windows operating system so why would you expect LrC to do anything different. You move the -2 files using LrC to ANOTHER folder and then do the rename using preserved filename. This is not a LrC issue, it is an Operating System rule that the two files can not be named the same in a single folder.
