zenoss 3.0 rc1 upgrade error

Hi,

i've an issue upgrading my test install 2.5.2 to 3.0rc1

Daemon: zeoctl Error: no program specified; use -p or -C
For help, use /opt/zenoss/bin/zeoctl -h

what can i try?

i found this issue in a ticket ---> http://dev.zenoss.com/trac/ticket/6629 (but the resolution is a won't fix)

Here my upgrade step:

1- install fresh zenoss 2.5.2 on a test machine

2- restore 2.5.2 backup on the test machine

3- remove not 3.0 ready zenpack

4- install pre-upgrade zenpack and wait until zencatalog ends.

5- upgrade zenoss from 2.5.2 to 3.0 rc1

Regards

Andrea
