I tried to migrate the zimbra from one machine to another machine.

Both machine OS: FC4
Zimbra Versions: zcs-3.0.0_GA_156

I installed zimbra system on the new machine at first and put the backup folder /opt/zimbra from original machine in the new machine. When I start the zimbra service, error came:

Starting ldap...Done.
Starting antispam...Done.
Starting antivirus...Done.
Starting logger...Done.
Starting mailbox...Done.
Starting mta...Done.
Starting snmp...Done.
Starting spell...FAILED
Syntax error on line 232 of /opt/zimbra/conf/httpd.conf:
Cannot load /opt/zimbra/httpd-2.0.54/modules/libphp5.so into server: /opt/zimbra/httpd-2.0.54/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied

Any step I have missed?
