Leena,

This is not possible with physical partitioning schemes. If you were using
Logical Volume Management (LVM) this would have been possible.  There could
be a slightly hackish workaround by making a bit-by-bit copy of all
partitions, re-partitioning so that sizes are changed but device volume
numbers are the same (i.e. the partitions have the same naming scheme as
before e.g. /dev/sda1 = /, /dev/sda2 = /home) and then restoring the root
partition back on to the (now larger) partition.

I have tried this on VMWare and it works. However I'm not sure if this is
the best approach for a physical machine.

Regards,

Ritesh
