I have an Hetzner server initially installed with this script with a configuration like this:

DRIVE1 /dev/sda
DRIVE2 /dev/sdb
    
SWRAID 1
SWRADLEVEL 1
    
BOOTLOADER grub
HOSTNAME machine.domain.com
    
PART /boot ext3  512M
PART lvm   vg0   all
    
LV vg0 root / ext4 25G
LV vg0 swap swap 8G
LV vg0 tmp /tmp ext4 8G
LV vg0 home /home ext4 10G
LV vg0 docker /var/lib/docker ext4  25G
LV vg0 server /srv ext4 1024G
LV vg0 backup  /srv/backup ext4 1024G

I would like to change the OS only and therefore I am willing to format only / (and possibly /home).
Is it possible to achieve this with this script ?
Thanks in advance for your help.

Installimage is targeted for fresh installations. However there are some UNSUPPORTED options for doing a re-install and preserving data.
Take a look at

PRESERVE_FS and REUSE_FSTAB allows to skip partitioning and preserve certain mountpoints.
