The 3.1.1 Migration Tool converts backup sets created by AEE 3.0.x GUI for use by AEE 3.1.1. AEE 3.0.x backup sets must be migrated to AEE 3.1.1, before they can be used by AEE 3.1.1.
The migration tool transforms AEE 3.0.x backup set configuration files into AEE 3.1.1 configuration files. Special configurations, including configuration files edited manually, may require Zmanda Customer Support to complete the migration process.
To upgrade AEE 2.6.4 backup sets, install AEE 3.0.2 first. After upgrading to AEE 3.0.2, then install AEE 3.1.1
To upgrade your existing installation of AEE 3.0, consider creating a manual backup of /etc/amanda and /etc/zmanda:
tar cvjf /var/log/aee.3.0.etc.tar.bz2 /etc/amanda /etc/zmanda
Next, read "Project:Amanda Enterprise 3.1", and follow the directions provided for downloading and installing AEE 3.1. Specifically, read and follow the instructions in Amanda Enterprise Edition 3.1 Release Notes for preserving your existing backup sets.
After successfully installing AEE 3.1 using the "preserve" option, login to http://network.zmanda.com. Go to the "Download" tab and click the link "OPTIONAL: Configuration Migration Tool".
Download, extract, and save the file to:
/opt/zmanda/amanda/apache2/htdocs/zmanda-aee/ZMC/BackupSet/Migration.php
If the location above does not exist, then AEE 3.1 has not been successfully installed (please refer to the links above for help). After saving the Migration Tool to the location above, type:
chown amandabackup /opt/zmanda/amanda/apache2/htdocs/zmanda-aee/ZMC/BackupSet/Migration.php
chmod u+r /opt/zmanda/amanda/apache2/htdocs/zmanda-aee/ZMC/BackupSet/Migration.php
Rarely, an AEE 3.0 backup set might contain unusual settings that prevent the Migration Tool from completing successfully. Please make sure you have the most recent version of the Migration Tool. If a newer version of the tool is available, then install the newer version of the Migration Tool, and manually delete /etc/amanda/<backup set name>/zmc_status. Now, migration can be repeated using the "Migrate" button on the ZMC Admin|backup sets page.
