Hello folks,
I just tried to upgrade FC4+3.1.3 OpenSource to FC5+4.0.2 with the following steps. If you guys know the better ways or ideas, kindly let me know.

1. Backup /opt/zimbra dir and keep this safe place.
ex. # tar cvfz zimbra_313.tgz /opt/zimbra (I correct the command because of typo in previous post...)

2. Install FC5 from scratch.
2-1. Disable SELinux
2-2. Diable firewall
2-4. yum -y update
2-5. Install requirement software (Sudo, libidn, cURL, GMP, etc...)
2-3. Install Openssl097a (just in case)

yum install openssl097a
cd /lib
ln -s libssl.so.0.9.7a libssl.so.5
ln -s libcrypto.so.0.9.7a libcrypto.so.5

3. Install 4.0.2 with FC5 binary.

4. Stop ZCS and remove /opt/zimbra

5. Restore 3.1.3 dir to /opt/zimbra

6. Start the Upgrade to 4.0.2 with FC5 binary

7. Just before running server during installation (when the message "Notify Zimbra of your installation?" appears), do the followings to avoid further "zmprov" errors.
7-1. remove rm /opt/zimbra/lib/jars/commons-httpclient-2.0.1.jar
7-2. Renew SSL certificate
7-3. Remove Logo.gif in Template directory (not necessary in some cases)

(by root user)
rm -rf /opt/zimbra/ssl
mkdir /opt/zimbra/ssl
chown zimbra:zimbra /opt/zimbra/ssl
chown zimbra:zimbra /opt/zimbra/java/jre/lib/security/cacerts
chmod 644 /opt/zimbra/java/jre/lib/security/cacerts
rm -rf /opt/zimbra/lib/jars/commons-httpclient-2.0.1.jar
rm -rf /opt/zimbra/wiki/Template/Logo.gif(not necessary in some cases)

keytool -delete -alias my_ca -keystore /opt/zimbra/java/jre/lib/security/cacerts -storepass changeit
keytool -delete -alias tomcat -keystore /opt/zimbra/tomcat/conf/keystore -storepass zimbra

zmcreatecert
zmcertinstall mailbox /opt/zimbra/ssl/ssl/server/tomcat.crt
zmcertinstall mta /opt/zimbra/ssl/ssl/server/server.crt /opt/zimbra/ssl/ssl/server/server.key

Thanks,
