Migration from OTRS Znuny

[kobylevy]

Hi,

We have running OTRS 6.0.4 which we installed from source, therefore it making difficulty to upgrade with the rpm.

I installed new server (Znuny 7.1) via rpm and would like to migrate my OTRS data to my new system.

Beside of copying templates and customer skins, the main chalange is the DB.

Plesae advice on best option (I'm thinking of duplicate my exiting server, upgrade to latest (the new copied server), and dump/restore on new server).

Thanks,

Koby

Hi Flo,

I already upgrade to all those version on my lab and it working.

But for production (which prefeing to use fresh new server with RPM installation), I need all DB data to new server, so I dont have migration process, only dump/restore.

Thanks,

Hi,

bring the new server online.
stop the services on the old
do a backup.pl take all the files and do a restore.pl on new system (scripts are in $HOME/scripts)
start the new server/services
do a migration if needed

Hi,

my problem is that on new server I have znuny 7.1 (znuny schema, user....), while on old otrs the DB structure is diffrent.

Hi,

you have to do the migration on new server. You can not merge the two databases.
drop the new database
backup the old
move to new server and restore there
do the migration from doc.

Thanks Flo,

I will try.

Just one last question, I will dump old server, drop DB on new, restore old on new.

About migration, should I run the migrate scrtips for all versions or I can run the last one?

scripts/MigrateToZnuny6_1.pl
scripts/MigrateToZnuny6_2.pl
scripts/MigrateToZnuny6_3.pl
scripts/MigrateToZnuny6_4.pl
scripts/MigrateToZnuny6_5.pl
scripts/MigrateToZnuny7_0.pl

Hi,

please read the docs

https://doc.znuny.org/znuny_lts/release ... pdate.html

Use the following pages as a guide to updating Znuny. Each version is individual, as the instruction differ from version to version, even if they are similar.
If you are updating over multiple versions, please know that you must update to each minor version along the way.

cheers
