[rt-users] 3.8.2 to 4.2.3 Upgrade
Hi I am planning to upgrade our RT instance and move it to a virtual machine. As I want to keep RT downtime to a minimum, I plan to install RT 3.8.2 on the new VM, import the database and settings from the current instance and then proceed with the upgrade. Is this the best way to do it? Can you guys offer any suggestions? Regards, Jim -- RT Training - Dallas May 20-21 http://bestpractical.com/training

Is this the best way to do it? Can you guys offer any suggestions? the way I do: - setup a new VM (often 3.8 RT instances are running on old OS ;)) - install stock RT 4.2.3 - apply back your patch, plugins, ... - import current DB, measure time needed - run upgrade, measure time needed - test - if everything is ok, plan the real upgrade: - stop mail/http on prod server - dump/restore on new server - run upgrade - start mail/http on new server - test - play with dns/ip to make the new server be the production one this way you can safely do the upgrade, test, and now exactly the downtime to plan. -- Easter-eggs Spécialiste GNU/Linux 44-46 rue de l'Ouest - 75014 Paris - France - Métro Gaité Phone: +33 (0) 1 43 35 00 37- Fax: +33 (0) 1 43 35 00 76 mailto:elac...@easter-eggs.com - http://www.easter-eggs.com -- RT Training - Dallas May 20-21 http://bestpractical.com/training

We've done it like this: - install fresh RT version same as the production one - import the database from the current production - run and update prior to the last version of RT - once we've tested that everything is fine, started the update procedure in the production RT There some specific steps that you should follow (for example when you dump your current database don't forget to use --default-character-set=binary) but i'm sure you've read whole documentation already ;) Happy hunting, and good luck upgrading.
