Step 1: Install BART 2.3 in a separate directory than BART 2.0. Refer Section 3.1 for BART 2.3 installation.Step 2: Save a copy of your BART 2.0 configuration file. The default location and file name is /usr/edb/bart2.0/etc/bart.cfg).After installing BART 2.3, you can use this same configuration file for BART 2.3, but ensure you use a new directory for the BART backup catalog and not the same directory used by BART 2.0.Step 3: Use the following command to remove BART 2.0.Step 4: In the newly created /usr/edb/bart/etc directory, place the configuration file bart.cfg that you saved in Step 1 from BART 2.0. (Note that this is the default location of the configuration file. The -c option can be used with BART subcommands to specify an alternative configuration file name or location. See Section 5.3 for information.)Ensure the backup_path parameter of the BART 2.3 configuration file is set to a new directory and not to any existing BART 2.0 backup catalog. In other words, new full backups and incremental backups taken using BART 2.3 must be stored in a new BART backup catalog.
• If you are installing BART 2.3 on a remote host on which incremental backups are to be restored, (in other words, this is not the BART host), then the content of the BART 2.3 etc subdirectory does not need the addition of the bart.cfg file.Step 5: Adjust the setting of the PATH environment variable to include the directory location of the BART 2.3 bin subdirectory in the ~/.bashrc or ~/.bash_profile files of the following user accounts:
• The BART user account on the BART host. See Section 4.1, Step 3 for information.
• Step 6: On any remote host on which incremental backups were restored using BART 2.0, the same BART 2.3 installation and BART 2.0 removal process must be performed in a similar manner as on the BART host.After upgrading to BART 2.3, you must take a new full backup of your system before performing an incremental backup.BART 2.3 cannot be used to perform incremental backups from parent full backups or parent incremental backups that were taken using any of the older BART versions than 2.3. Taking incremental backups using BART 2.3 is possible only from parent full backups and parent incremental backups that were taken using BART 2.3.
