Is it possible to have the same swap device names in RHEL 6 as the ones presented in RHEL 5?

Issue

• The command 'swapon -s' shows /dev/mapper devices in its output:

[root@rhel5 ~]# swapon -s
Filename                                Type            Size    Used    Priority
/dev/mapper/vg00-swap1                  partition       2031608 377632  -1
/dev/mapper/vg01-swap                   partition       15728632        0

• While the same command shows /dev/dm-X devices in RHEL 6:

[root@rhel6 ~]# swapon -s
Filename                                Type            Size    Used    Priority
/dev/dm-0                               partition       3080184 0       -1
/dev/dm-9                               partition       1048568 0       -2
/dev/dm-10                              partition       131064  0       -3
