2. Install up to date Perl, Apache 2.x and MySQL 5.x on a new system
(this is in progress now). Install OTRS 2.2.7 but skip initalization
of the database (is it correct?)
That seems okay. You can even initialize the database to set it up
correctly.
3. Run ~otrs/scripts/backup.pl -d /var/tmp -c bzip2 -t fullbackup on
an old 2.0.x system. This should give a complete packed copy of an old
installation.
Yes, but are you sure you need that? The complete backup includes the
2.0.x application.
If you have not changed anything in the Kernel/Output/HTML folder
(i.e. created a new theme or hacked about an existing one), you only
need your database, configuration and any attachmenths the tickets may
have.
You can create a backup of the database manually:
mysqldump -u otrs -p otrs > otrs-database.sql
It'll prompt you for the otrs password to the database.
scripts/backup.pl also creates a dump of the database. Maybe that part
is done before your backup crashes, look in /var/tmp (your specified
output directory).
The configuration of OTRS is simply extracted via SysConf in the Admin
menu. There's a download-button.
4. Suppose I got a correct nice backup of the 2.0.x install. Ok now I
copy the backup to a new system and run restore but database only (BTW
how do I do this, namely - restore database without overwriting
everything else?
Copy your database backup to the new system, then:
mysql -u root -p otrs < otrs-database.sql
It'll prompt you for the otrs password to the new database. I don't
know if you have this yet since you haven't installed the database on
the new system. You can set it up manually, though:
mysql -u root -p mysql
grant all on otrs.* to 'otrs'@'localhost' identified by 'your otrs
password goes here';
This is assuming your database is called 'otrs'.
5. Ok this way or that, but I have a copy of old DB and config on a
new system, but with 2.2.7 code. Now I run conversion scripts
2.0-to-2.1, 2.1-to-2.2.
Yes.
Voila? Will I have a ready new OTRS 2.2.7 system with all my data
preserved at this moment?
Probably. As long as you haven't switched DNS or IP with the original
server, you're able to log in to your new system and check it out
before going live.
