Dear collegues, we are running OTRS 2.0.x in production on FreeBSD 6.x + apache 1.x. Now we need to secure some minimal (in order of minutes) interruption of service while moving to 2.2.7. Here below is my step-by-step plan to achieve this; what I'd like to ask you is your comments, additions and suggestions - is the plan correct? what are my mistakes? is it suboptimal, maybe? Thanks in advanse. 1. Install new hardware server, install and configure FreeBSD 7-STABLE (as of today) on it. Install up to date ports and packages. (this has been DONE). 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?) 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. Problem #1. bash-2.05b# time ./backup.pl -d /var/tmp -c bzip2 -t fullbackup Backup /var/tmp/2008-07-04_11-58/Config.tar.gz ... tar: Kernel/Config/GenericAgen*.pm: Cannot stat: No such file or directory ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ????? tar: Error exit delayed from previous errors. failed Backup /var/tmp/2008-07-04_11-58/Application.tar.gz ... ^Cfailed ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ went asleep, probably forever Dump MySQL rdbms ... done Compress SQL-file... done real 25m30.840s user 15m11.339s sys 0m32.480s bash-2.05b# What I'm doing wrong? Or do I need to stop apache before running ./backup.pl ? 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? Or maybe it's better to restore full backup first, and install 2.2.7 over it then? 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. Voila? Will I have a ready new OTRS 2.2.7 system with all my data preserved at this moment? Thank you for your time and help! WBR, Andrew
