Edited after suggestion from @CMaster:
I tried google to find a solution for the same but unfortunately nothing was available, so I communicated with the customer-care of IRCTC (011-39340000) and asked for the relevant solution. The executive told me that the same was not possible for tickets having CKWL status. Later when my ticket was confirmed(status changed to CNF), I tried changing the boarding point again from the IRCTC website and the same was done without any hassle.
