Whenever I run any LVM related command the old volume group configuration information is saved in /etc/lvmconf/vg
Please let me know what is the need of saving old configuration info.

Re: Logical Volume
LVM will take care if .. :)
# lvextend -L 1024 /dev/vg01/lvol4
Logical volume "/dev/vg01/lvol4" has been successfully extended.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf --> it will automatically backup
if you want double sure, you can also run "vgcfgbackup"
man vgcfgbackup

SolutionGood practise.always have OS recovery tapes
make_tape_recovery -> will backup all OS configuration (including your LVM)
manual ways of doing as per my knowledge.
All your vg information are stored under below location
# cd /etc/lvmconf
# cp -p vg01.conf.old vg01.conf.old.org -> "making a local backup copy"
/etc/lvmconf] # ls -lrt
total 6032
-rw------- 1 root sys 297984 Mar 12 08:34 vg01.conf.old
-rw------- 1 root sys 297984 Mar 23 09:14 vg01.conf
-rw------- 1 root sys 297984 Mar 23 09:14 vg01.conf.old.org
Again, please take note "make_tape_recovery" is the best way of backing up your OS configuration file.
