[SOLVED] Upgrading from 4.5.9 to 5.0.2 on Cent OS 5.

[aoddy]

These are steps for upgrade Zimbra 4.5.9 to 5.0.2.

1. Download new version from www.zimbra.com

[root@mail] # mkdir Program; cd Program
[root@mail] # wget -c http://files.zimbra.com/downloads/5....0130221917.tgz

2. Unzip new software.

[root@mail] # tar xvfz zcs-5.0.2_GA_1975.RHEL5.20080130221917.tgz

3. Upgrade new libtool-ltdl package.

[root@mail] # yum install libtool-ltdl

4. Stop current Zimbra service.

[root@mail] # su - zimbra
[zimbra@mail] $ zmcontrol stop
[zimbra@mail] # exit
[root@mail] #

5. Install Zimbra version 5.0.2.

[root@mail] # cd zcs-5.0.2_GA_1975.RHEL5.20080130221917
[root@mail] # ./install

7. After you upgraded , you can not sent email and you found warning in file /var/log/zimbra.log

postfix/smtpd[8439]: warning: problem talking to service rewrite: Success
postfix/master[7626]: warning: process /opt/zimbra/postfix-2.4.3.3z/libexec/trivial-rewrite pid 9809 exit status

8. Fix this problem by change start_tls option in file ldap-*.cf in path /opt/zimbra/config/ from Yes to No and this is script for change it in all files.

#!/bin/bashfor x in ldap-scm.cf ldap-transport.cf ldap-vad.cf ldap-vam.cf ldap-vmd.cf ldap-vmd.cf;
do
echo “File : ${x}”;
cp $x $x.bak;
sed -i s/”start_tls = yes”/”start_tls = no”/g $x;
done

9. Assume name of this script is change_start_tls_yes2no.sh. Change mode of this script and run it.

[root@mail] # cd /opt/zimbra/conf/
[root@mail] # ls -l change_start_tls_yes2no.sh
-rwxr-x— 1 zimbra zimbra 196 Mar 6 09:45 change_start_tls_yes2no.sh
[root@mail] # chmod +x change_start_tls_yes2no.sh
[root@mail] # ./change_start_tls_yes2no.sh

10. Restart new Zimbra service.

[root@mail] # su - zimbra
[zimbra@mail] $ zmcontrol stop
[zimbra@mail] $ zmcontrol start
[zimbra@mail] $ zmcontrol status

Thanks for the guide Probably worth adding before step 5 take a backup of /opt/zimbra, and also test that backup to ensure you have a roll back point

Thank you so much for this! I was just doing an upgrade from 4.5.9 to 5.0.6 and got the libtool-ltdl missing error; not being a Linux person I had a bit of a panic. I found your post and the direction to download the new package and voila! Problem solved.

I love this forum. Zimbra rocks!
