I've upgraded from ZCM 11 SP1 to SP2 (SLES 11 SP1) without any errors.

To install ZCM 11 SP1 in a virtual machine i previous used the following
partions under SLES11 considering the recommendations:

/opt ext3 10 GB
/var/opt ext3 60 GB

Before upgrading to SP2 i had about 4.5GB free space on /opt, after
upgrading there are only 1.3GB free space left, so i think a future upgrade
to SP3 will fail.

Can anyone please give me a hint, which directories have to be cleaned
rsik-free so that my /opt partion will have enough free space for future
