I have worked out an example procedure to demonstrate the concept:

############################################
#
# On the 32bit Machine, as root:
#

/etc/init.d/zimbra stop
mkdir /opt/zimbra/openldap-data.bak
chown -R zimbra.zimbra /opt/zimbra/openldap-data.bak
sudo -u zimbra /opt/zimbra/libexec/zmslapcat /opt/zimbra/openldap-data.bak/
rsync -av --delete-after /opt/zimbra/ /mnt/my_usb_harddrive/zimbra.32bit/

############################################
#
# On the 64bit Machine, as root
#

* Make sure zimbra uid and gid match.
* All other relevant aspects of the system match (hostname, IP Address, etc.)

# Copy 32bit data to new system, or mount existing volume
rsync -av --delete-after /mnt/my_usb_harddrive/zimbra.32bit/ /opt/zimbra/
rsync -av --delete-after /opt/zimbra/conf/ /tmp/conf.32bit/

# Unpack ZCS, and install only necessary binaries
tar -C /tmp -xvzf zcs-NETWORK-5.0.7_GA_2450.UBUNTU6_64.20080630192957.tgz
cd /tmp/zcs-*
dpkg -i packages/zimbra-ldap_5.0.7_GA_2450.UBUNTU6_64_amd64.deb
packages/zimbra-core_5.0.7_GA_2450.UBUNTU6_64_amd64.deb
rsync -av --delete-after /tmp/conf.32bit/ /opt/zimbra/conf/

# Help binaries to find the right libraries
for i in /opt/zimbra/zimbramon/lib/
/opt/zimbra/zimbramon/rrdtool/lib/perl/5.8.7/
do
    cd $i
    mv i486-linux-gnu-thread-multi i486-linux-gnu-thread-multi.bak
    ln -s x86_64-linux-gnu-thread-multi i486-linux-gnu-thread-multi && echo OK
    cd -
done

# Import the exported LDAP data with the 64bit binaries we just installed
cp -f /opt/zimbra/openldap-data/DB_CONFIG /tmp/DB_CONFIG
/bin/rm -rf /opt/zimbra/openldap-data/*
cp /tmp/DB_CONFIG /opt/zimbra/openldap-data/DB_CONFIG
mkdir -p /opt/zimbra/openldap-data/logs /opt/zimbra/openldap-data/accesslog/db
/opt/zimbra/openldap-data/accesslog/logs
chown -R zimbra:zimbra /opt/zimbra/openldap-data
/opt/zimbra/openldap/sbin/slapadd -q -b '' -f /opt/zimbra/conf/slapd.conf -cv
-l /opt/zimbra/openldap-data.bak/ldap.bak

# Proceed with the upgrade as normal
./install.sh

kod upgrade-a na zimbra-7 na našoj infrastrukturi ovo smo praktično odradili.
