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:[email protected] - http://www.easter-eggs.com -- RT Training - Dallas May 20-21 http://bestpractical.com/training
