Compatibility:
--------------
As always, both the Director and Storage daemon must be upgraded at
the same time.
- The new pruning algorithm will not allow to prune jobs that are essential to
- restore since the last Full backup. (TODO: see for an option...)
-
Older 5.0.x and 3.0.x File Daemons are compatible with the 5.2.0
Director and Storage daemons. There should be no need to upgrade older File
Daemons.
+================== Warning !!!!!! ==========================
+
+ The new pruning algorithm will not allow to prune jobs that are essential to
+ restore since the last Full backup. Pruning of volumes are not affected.
+
+New Catalog format in version 5.2.0
+-----------------------------------
+This release of Bacula uses a new catalog format. We provide a set of
+scripts that permit to convert a 5.0.x (version 12) catalog to 5.2.0 (version
+14). The Bacula project rpms distributed on Source Forge will automatically
+detect the database change and do the upgrade for you. We strongly
+recommend that you save a copy of your existing database before upgrading
+using rpms.
+
+The simplest way to upgrade the database assuming you are building from
+source:
+1. Stop any current version of Bacula from running.
+2. Save a copy of your existing database.
+3. Configure, build, and install the 5.2.0 version of Bacula
+ Note the new ./configure options in the manuals see the link
+ at the bottom of this file.
+4. cd <your-scripts-installation-directory>
+5. ./update_bacula_tables
+6. If you have multiple catalogs, edit the update_bacula_tables
+ script and put the name of another database, and then
+ execute the script again. Repeat this until all Bacula
+ catalogs have been updated.
+7. Start the new Bacula. If everything worked, it should
+ not print any error messages.
+
+If you start from scratch, you don't need to run the update_bacula_tables
+script because the create_bacula_tables script automatically creates the new
+table format. However, if you are using a version of Bacula older than 5.0.0
+(e.g. 3.0.3) then you need to run the update_bacula_tables script that will
+be found in the <bacula>/src/cats directory after you run the ./configure
+command. As mentioned above, before running this script, please backup your
+catalog database, and when you do running it, be sure shutdown Bacula and be
+aware that running the script can take some time depending on your database
+size.
