  2. Open am administrative command prompt and run the following command:
Syntax : mklink /D "path_to_new_symbolic_link  "path_to_old_folder”
Example : 
C:\Program Files\EMC NetWorker\Management\GST>mklink /D "C:\Program Files\EMC NetWorker\Management\GST\postgres_latest" "C:\Program Files\EMC NetWorker\Management\GST\postgres\11.1"
symbolic link created for C:\Program Files\EMC NetWorker\Management\GST\postgres_latest <<===>> C:\Program Files\EMC NetWorker\Management\GST\postgres\11.1
