Thanks to Marcmac we now have upgrade scripts(released under the terms of the MPL), which are attached to this message.

Here are the steps to upgrade if the new M2 build has not been installed:

1. As the zimbra user:
2. untar the upgrade.tgz file (tar xzvf upgrade.tgz)
3. find the upgrade script (cd Upgrade)
4. execute the upgrade script (upgradeM1M2.pl)
5. Install the new build. Answer "Y" to do you wish to upgrade.
6. Done!

If the new M2 build has already been installed:

1. As the zimbra user:
2. stop the zimbra software (zmcontrol shutdown)
3. make sure it stopped (ps -ef | grep zimbra)
4. untar the upgrade.tgz file (tar xzvf upgrade.tgz)
5. find the upgrade script (cd Upgrade)
6. execute the upgrade script (upgradeM1M2.pl)
7. start the zimbra software (zmcontrol start)
8. Done!

Notes:

The following error may be displayed during the install.sh process: "M2: integer expression expected". This error can be ignored. The install will complete normally.
