You can mount the var partition for another boot volume:

 ls /dev/mapper/*_var

will show the LVM objects containing var partitions. You can mount the one of those partitions (from HD1.2) as follows ...

 mkdir /mnt/alt_var

 mount -o ro /dev/mapper/vg--db--sda-set.2._var /mnt/alt_var

 ls /mnt/alt_var/local/ucs

You can then copy ucs files from the mounted partition to /shared.

Once you have finished, remember to unmount 

 umount /mnt/alt_var

Of course, you can also mount the /config volume in a similar fashion.

Remember to mount the alternative volume as read-only (-o ro) so you cannot change anything and cause a config issue that may prevent system startup.
