Is there a way to move the location of ICP private image registry of an installed ICP?

Question

I am running low on diskspace on the drive where the ICP private image registry is located. I know it's possible to specify a location for "/var/lib/registry" using a bind mount BEFORE ICP installation. Is there a procedure to safely move the location of ICP private image registry on an existing ICP cluster?

How to move /current/directory to another partition/disk

Once you have added extra disk, partitioned it, created the filesystem, and are ready to move /current/directory to it; take the following steps:

Assuming /dev/xvdc11 is the created partition with ext4 file system

# create a temp mount point and mount your new partition
mkdir /mnt/dirName
mount /dev/xvdc11 /mnt/dirName

# confirm that it is mounted.
df -h

# copy current directory content to the temp mount point
rsync -aqxP /current/directory/* /mnt/dirName

# use bind mount to set the new location
mount --rbind /mnt/dirName /dirName

# unmount and delete the temp mount point
umount /mnt/dirName
rm -rf /mnt/dirName

# persist this change across system reboots
echo "/dev/xvdc11   /current/directory   ext4   defaults   0   0" >> /etc/fstab
