Thanks RudiC & MadeInGermany for your replies, sorry for responding late.
While googling around I got a really nice article which helped me to achieve my goal.
How to shrink a default install LVM PV to create another partition
However, in my scenario I used this link as a reference because I used my swap partition to shrink, hence didn't required to boot system in rescue. Just did swapoff & shrink partition & carried out remaining steps from above link.
Thanks,

dtc_kill_vps_disk
dtc_kill_vps_disk(8) System Manager's Manual dtc_kill_vps_disk(8)
NAME
dtc_kill_vps_disk - destroy LVM disks for freeing space
SYNOPSIS
dtc_kill_vps_disk VPS_NUMBER [ lvm|loopback ]
DESCRIPTION
dtc_kill_vps_disk This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.
This script is used to delete a partitions that was used by a VPS. It will delete the normal partition that was used as a root disk, and
the swap partition.
dtc_kill_vps_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.
OPTIONS
VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group called
lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap.
IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then this script will
create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS.
EXAMPLE
dtc_setup_vps_disk 04 lvm
This will delete the 2 LVM partitions that were used by the VPS named xen04, the first one being the root partition, and the second one
being the swap partition.
