upgrade zimbra from 5.0.11 to 5.0.16

[luka123]

Hello..
I m new at zimbra administration and i need some informations abouth zimbra.
We are running zimbra Release 5.0.11_GA_2695.RHEL5_64_20081117021643 RHEL5_64 NETWORK edition on two RHEL 5.2_x86_64 servers (mta and store). we must restart zimbra-store every week beacuse of zimbra logger problem. (zmcontrol stop , ps aux |grep logger , kill all logger , zmcontrol start). I found informations on forum that this bug isn't present in new release 5.0.16 . does someone have some experiences with upgrading zimbra from 5.0.11 to 5.0.16 on mta and store server? How its with license during upgrading?

Regards

Welcome to the forums

Once you have taken all the necessary cold backups I believe you should upgrade the store and then the MTA. Just make sure you shut down all the ZCS services and that the logger service has indeed stopped. I would recommend using /etc/init.d/zimbra stop.

Uxbod thanks for reply...

our zimbra mta and store is running on vmware esx server soo with backu wont be a problem. we will create snapshot before start of ugrade. Does the old license for version 5.0.11 works on 5.0.16? so the steps for upgrade are :
-make backups mta store
-first upgrade store and then mta are those instructions good?
Before you begin, stop all the servers in your ZCS environment. On each
server, as zimbra type zmcontrol stop.
Important: Upgrade the servers in the following order: LDAP server, MTA
server, and then mail store server. The LDAP master server should be running
as you upgrade the other servers.
1. Log in as root to the Zimbra server and cd to the directory where the
Zimbra Collaboration Suite upgrade archive tar file is saved (cd /var/tmp).
Type the following commands:
tar xzvf zcs.tgz, to unpack the file
cd [zcsversionfullname], to change to the correct directory
./install.sh, to begin the upgrade installation
The upgrade script begins by checking for an existing installation.
2. The Zimbra software agreement is displayed. Read this software license
agreement and press Enter.
3. The installer checks for prerequisites. If any are missing, the upgrade
stops.
4. When you upgrade the mail store server, the installer displays Do you want
to verify message store database integrity (Y) is displayed. The default is
Yes. This step runs zmdbintegrityreport to verify that the MySQL® database
is not corrupt before upgrading to the latest ZCS.
Running zmdbintegrityreport can take minutes to an hour to run, depending
on your system size and disk bandwidth. It is preferable that you run
zmdbintegrityreport at the time of the ZCS upgrade. If you choose to skip
this now, the zmdbintegrityreport will run during a regular scheduled interval
after the upgrade is finished.
When the mySQL software versions are changed during upgrades, the
underlying database tables need to be upgraded. The zmdbintegrityreport
does this automatically during it’s first run and will report the changes.
These are normal and should not cause alarm when upgrading.
5. When you upgrade the mailstore server, the installer displays Do you want
to verify logger database integrity (Y) is displayed. The default is Yes. This
step runs zmdbintegrityreport -l to verify that the Logger database is not
corrupt before upgrading to the latest ZCS.
6. When Do you wish to upgrade? [Y] is displayed, press Enter to continue
The upgrade packages are unpacked.
7. The packages you want to install on the server should be marked Y. All
other packages should be marked N.
The upgrade checks that there is enough space to perform the upgrade. If
there is not enough space, the upgrade stops.
8. When The system will be modified. Continue? is displayed, type Y and
press Enter. The server is stopped and the older packages are removed.
The upgrade process verifies which version of ZCS is being run and
proceeds to upgrade the services, restores the existing configuration files,
and restarts the system. If you have a configuration with a large number of
accounts created, this can take a while.
9. When Configuration complete – press return to exit displays, press Enter.
The upgrade is complete. Continue to upgrade each server.
