Best way to upgrade live system from 2.4.x to 3.0.x

Hello List, I am concerned with the down time that appears to be involved when upgrading from 2.4.x to 3.0.x when following the procedures outlined in the UPGRADING document. Especially if after the upgrade we find some showstopper and have to revert. Anybody have any suggestions to mitigate the risks? -- Stephen Clark *NetWolves* Director of Technology Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark@netwolves.com http://www.netwolves.com

Clone your live system, then test, time and document the upgrade procedure,
then if everything goes OK in the cloned system it should work as expected
in live (and should in theory take less time as you will have documented
all the commands etc.).
Going from 2.4 has a number of changes to the GUI interface aswell, so
remember your users who will probably be on the phone to you asking where
everything is, if you have a cloned system you could give them something to
play with for a short period of time before the live is upgraded.

1) Clone your current system to a new box/virtual machine. 2) Dump the database to flat file. 3) Upgrade the new box. 4) Convert the database 5) Test 6) Swap the machines. Backout is as simple as turning the new machine off. And you get a backup of your current system (as one poster has recently experienced, upgrading your production system is a bad way to test OTRS upgrades. ) From: otrs-bounces@otrs.org [mailto:otrs-bounces@otrs.org] On Behalf Of Steve Clark Sent: Monday, May 07, 2012 4:20 PM To: User questions and discussions about OTRS.org Subject: [otrs] Best way to upgrade live system from 2.4.x to 3.0.x Hello List, I am concerned with the down time that appears to be involved when upgrading from 2.4.x to 3.0.x when following the procedures outlined in the UPGRADING document.
