Thanks Rory - much appreciated! :-) ________________________________ From: Rory To: User questions and discussions about OTRS. Sent: Tuesday, 8 September, 2009 16:28:48 Subject: Re: [otrs] Move data from live server to local version of OTRS Yes, it would still be best to install version 2.2.5 because you will still learn some things about upgrading from this version even if it is a different OS. If you have the same version software on each machine (mysql, apache and otrs) you minimise the impact that the different OS will have. There may still be some problems though. You should consider the VMware approach. Its a lot of extra work but cant give you a great test environment that you can reset again and again. http://www.vmware.com/products/server/ VMware Server 2 is free and (in case you don't know about it) will let you install linux on your windows XP machine. Have a look at some of the VMware Server documentation and see if you can get your head around the idea of how it sits together. If you did this you could have your linux install without having to get involved with what IT support. A linux install is a little daunting if its the first time you've done it but its not that difficult. If you want to go down that road then feel free to keep asking your linux questions in this thread and I'll answer what I can.

Thanks a lot Rory and Stephan.

My test machine is Windows and live is Linux.

I am afraid it is not an option to install Linux on the test machine as it is not supported by our IT department.

Do you still think I should install the same version of OTRS as live (2.2.5) on the test machine? ________________________________ From: Stephan Lang To: User questions and discussions about OTRS.

Hi,

I'd like to use VMware to test stuff. In this case you could use VMware Converter to create a virtual copy of your live server, but I haven't tried doing that with a Linux OS (what's your live server OS btw.?). With the live server duplicated and VMware snapshots you can test until everything works and by pretty sure that the live server will act the same way.

Yours sincerely

You can get the older versions from the FTP. If I remember you can do the install from the tar.gz file on windows.

Actually I will be required to make a fresh install of OTRS on the test machine ( a new Windows XP machine).

Is it possible to install the same version of OTRS (2.2.5) as the live version? All that seems available on the download page (http://otrs.org/download) is the latest version (2.4.4).

Hi Lev,

I would suggest that you rebuild the test machine to the same version as your production machine. Once done, dump the live database and then import it to the test DB and copy over your configuration. Once this is in place perform the upgrade procedure on the test machine taking note of any steps you needed to do that were out of the ordinary. It would be a good idea to isolate the machine on the network so that you don't send out test spam to your clients as Lars said. You could do that at the firewall or simply have a private network between your machine and the server.

Once you successfully complete the update process on your test box you have your upgrade path. You can now be confident that you can successfully upgrade your production server. Once you have upgrade the production server to the same level as the test server you are in a position to do some reliable backups, you could even swap the servers if needed.

For the DB backup, mysqldump is a very good tool but you will have trouble if you try to use it the way you've described. You would have to edit the dump file and delete all the data in the live database after each backup. I can see it being very laborious.

What you could do is this;

1. Create a second database on the test server i.e. otrs2 2. Dump the current live database to the otrs2 database. 3. Clear out the live database. 4. Perform future dumps to the first test database.

This way you will have a current backup of the production server and a historical backup of the database that you can connect to if you need to. When the performance of the production server is degraded again you could create a 3rd database on the test server and repeat the above steps with it. This would leave you with a current production backup and 2 historical backups.

Its not a nice way of doing things but it would do what you were looking for. There's always the alternative of getting new hardware to run the production server on :)

I hope that helps, Rory Clerkin

I see.

So there is no way to, say, dump the data, import the dump into the backup, delete the backed up data from the live system and then import only the new data into the backup a few months later?

Hi Lev,

...

Why is it not a good idea to do a dump every few months? Is it because the whole process is very time consuming? Or are there too many risks attached?

depending on the size of your DB, it can be very time consuming.

...

Where can I find more information about replication?
