7.13 UBUNTU 8.04 LTS to 7.2 UBUNTU 10.04 LTS on VMWARE and installing OPEN VM TOOLS
Had a successful migration form 7.13 on Ubuntu 8.04 to 7.2 Ubuntu 10.04 ( all 64 bit edition since 7.2 will be deprecated on ubuntu 8.04 )
Do all updates on Ubuntu
Disable zimbra on boot up. ( use webmin interface )
Upgrade to 7.2 ZCS for Ubuntu 8.04 version
Say yes for MYSQL db integrity check.
Upgrade sucessfull, however amavisd ( for antispam/antivirus ) will not start because of FQDN error.
Make changes to /opt/zimbra/conf/amavisd.conf.in ( the .in file overwrites the amavisd.conf everytime amavis services is launched.
Correct FQDN approrpriately.
Restart amavis using command amavisdctl restart
Very zimbra services are restarting properly -
zmcontrol stop / start
CLone or Backup your VM.
Proceeded with upgrade to Ubuntu 10.04 LTS
Shutdown ZImbra services.
apt-get install update-manager-core
The minumum contents of /etc/update-manager/release-upgrades should be
Answer yes to pretty much all the requests in the upgrades.
Launched ZImbra but it won't start at all :
Some error about perl came up.
Did some research on perl which comes standard with 10.04.
see this post
Proceeded to delete
deleted /opt/zimbra/zimbramon/lib/x86* directory where perl resides.
THen upgraded to 7.2 ZCS for UBUNTU FOSS ( 10.04 ) edition.
PLEASE DO NOT ACCEPT MYSQL INTEGRITY CHECK AS IT REQUIRES PERL.
Upgrade to 7.2 FOSS successfull.
with amavis ( antispam/antivirus ) still down.
redo the same thing for amavisd.conf.in as described above.
Zimbra 7.2 UBUNTU FOSS started like a charm.
Checked all logs and tested emails and access to admin console.
- Applied open vm tools on the fly
apt-get install linux-headers-virtual
apt-get install --no-install-recommends open-vm-dkms
apt-get install --no-install-recommends open-vm-tools
VM tools installed ( on vmware console it will read unmanaged )
Next step now is to script a zimbra cron job to stop zimbra services - Veeam Backup the VM and restart zimbra for automation.
Good luck to you all.
