Hi Ana,
I’ve now come to these steps after your suggestions:
1. Build a centos 7 server and install bacula from base i.e. 5.2.13 and
mariadb
2. Stop all bacula services on old server
3. Take a mysql dump of the old server’s bacula database. Mysqldump –u
root –p bacula > bacula.sql
4. Copy bacula-dir.conf, bacula-fd.conf, bacula-sd.conf, bconsole.conf
over to the new server + my custom config files under bacula-dir.d/ and
bacula-sd.d
5. Restore mysql dump onto new server – create database bacula, mysql –u
root –p < bacula.sql
6. Run /usr/libexec/bacula/update_mysql_tables on the new server (this I
checked upgrades the mysql db tables to version 14 J)
7. Start bacula daemons on new server and test by restoring etc.
Anything I missed?

Hi,
I have done some reading on bacula 7 and the 5.2.13 version in centos base. I
have decided to upgrade to centos7 and use the 5.2.13 version and not go to 7
just yet. (sorry for changing my mind L)
Don´t worry :). It is your choice. When you could, think of upgrading to
7.0.5. There are lots of improvements.
The reason for this is that centos7 has the version 5.2.13 in base.
My plan therefore is:
1. Build a centos 7 server and install bacula from base i.e.
5.2.13 and mariadb
2. Take a mysql dump of the old server’s bacula database.
Mysqldump –u root –p bacula > bacula.sql
3. Copy /etc/bacula directory over to the new server
Please, do not copy the whole directory. You will just need to copy your
bacula-dir.conf, bacula-fd.conf, bacula-sd.conf, bconsole.conf and other
customized confs that you could have.
4. Restore mysql dump onto new server
5. Run /usr/libexec/bacula/update_mysql_tables on the new server
6. Start bacula daemons
On the current server I have volumes under /home/bacula. Shall I also
take these over, for historic restores, should I need them? Or shall I leave
them and can restore from the old version if I need to?
You can move theses volumes to the new server and have all your backups in
just one server. It is your choice. Also you can keep the old one and have the
new one with new volumes, new director name, etc. This way you can also delete
your old volumes from the new catalog (and just have clients, storage, etc.
from the old one). Since you are going to have your old server running until
the new one works fine, you can do tests with this new environment and when you
assure this new environment, then you could set this new server as your only
Bacula server. I would prefer having just one server with all my backups there.
Is this a good plan for migrating to a new server and upgrading from
5.0.0 to 5.2.13?
If you are going to install a new server there is no need to install 5.0.0
version. You can install the 5.2.13 and restore your config files and catalog
to this new server.
Thanks all for all your help with this :D
You´re welcome.

Hi,
Thanks all for the replies. My requirement is to move to a centos 7 OS
with mysql as DB (current is 6). Here is what I’ve found from the instructions
provided by everyone (and for the benefit of someone in the future in my
situation):
Firstly, build a new centos 7 machine and do the following
1. Download 7.0.5 code. From
http://sourceforge.net/projects/bacula/files/bacula/7.0.5/bacula-7.0.5.tar.gz/download
- does this include bacula-sd, dir and fd?
yes. That includes director, file daemon and storage daemon.
2. Extract.
3. Install deps:
yum install mysql-devel gcc-c++ readline-devel zlib-devel
libacl-devel mtx postfix
4. Configure:
./configure --with-readline=/usr/include/readline
--disable-conio --bindir=/usr/bin --sbindir=/usr/sbin
--with-scriptdir=/usr/libexec/bacula/ --with-working-dir=/var/spool/bacula/
--with-logdir=/var/log --enable-smartalloc --with-mysql
5. Build:
make -j8 && make install && make install-autostart
6. Run update db script: ( Not sure about this step, please see
step 8)
/usr/libexec/bacula/update_bacula_tables
7. Copy over the config files under /etc/bacula/ to the new
centos 7 box with bacula 7. Will I need to run step 6
(/usr/libexec/bacula/update_bacula_tables) here?
You can do the update_bacula_tables in step 6.
8. Restart bacula daemons
I would recommend you do not start the daemons before the database
upgrade. So, here, I should say "start bacula daemons".
Please assist on the questions I have above, or is there a
better way I should be doing this? What about the volumes + files I have on the
current server, how can I take these across as well?
A better way would be to have the Bacula´s upgrade in the same
machine, if you could. This way you would not need to copy the volumes to the
other host. The volumes should be in same directory that they were before (you
should configure and create the same archive device in the new host).
IMHO, this should work fine :).

Hi Wagar,
Is that clear for you? I saw the other posts. So you have two
options: upgrade to 5.2.13 using yum or remove your actual version and build
from source the 7.0.5 version. If you decide to build from source, remember to
do a backup of your conf files (they shouldn´t be replaced, but...). You can
upgrade from 5.0.0 to 7.0.5, since you are going to upgrade your database from
a version 12 to version 14.
You can find in the manual:
10.2 Upgrading Bacula
10.6 Building Bacula from Source

Ana

Hi Ana,
The version I am running is 5 exactly:
Version: 5.0.0 (26 January 2010)
Selecting database version I get VersionID = 12
5.0.0 is in the base repo but I can’t see 5.2.13 in there.
What’s the best way to get to 5.2.13 first? Where can I get
update_bacula_tables from + documentation :P

Hi!
Which Bacula´s 5 version do you have? I´ve upgraded from 5.2.13
to 7.0.5 with no problems (host XenServer). I´m affraid version 5.0.X has a
prior database version than 5.2.13, so it will be nice to take a look at your
actual database version (you can make a select to list contents from Version
table). If you have an earlier database version then 14, you will need to do an
update_bacula_tables after upgrading software and before starting using Bacula.
Best regards,
Ana

Hi all,
I am currently using version 5 of bacula dir,sd and fd. Is
there any documentation on upgrading to the latest release from this version.
Will I have to first upgrade to 7.0 or can I upgrade directly to 7.0.5. I am
also upgrading the base OS from Centos 6 to Centos 7. Which problems can I
expect?
Any help will be greatly appreciated.
