convert EXT2 to EXT3

I converted all EXT2 to EXT3 except one which is our / .

this is last file system for convert,
Is it possible the running file system convert to EXT3 without any lost data or reinstallation.



Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/sda7 ext2 10080488 9305864 262556 98% /
/dev/sda5 ext3 10080488 8777584 790836 92% /backup
/dev/sda1 ext2 1004024 10868 942152 2% /boot
/dev/sda3 ext3 15116868 1708268 12640696 12% /home
none tmpfs 515220 0 515220 0% /dev/shm
/dev/sda8 ext3 5036284 144580 4635872 4% /tmp
/dev/sda6 ext3 10080488 3010460 6557960 32% /var
/dev/sda2 ext3 15116868 10315824 4033140 72% /var/spool/mail

 

This is a trial and error thing. Make a backup before you try.
