Drupal Upgrade Plan 2008

From OSGeo
Jump to navigation Jump to search

Upgrading the OSGeo Drupal CMS is a complicated task further complicated by the use of multi-site configuration. To upgrade from current 4.7.x to the newest 5.3 version the following steps should be taken (doubles as a check list):

Time estimation

I estimate that the total read-only time for the OSGeo sites will be around 1 day if everything goes according to plan, this does not include the preliminary tasks which have to be completed prior to doing the upgrade.

Preliminary tasks

DNS Changes

  1. create entry CNAME dev.osgeo.net test.osgeo.net.
  2. create entry CNAME edu.osgeo.net test.osgeo.net.
  3. create entry CNAME fdo-test.osgeo.net test.osgeo.net.
  4. create entry CNAME mapbender-test.osgeo.net test.osgeo.net.
  5. create entry CNAME mapguide-test.osgeo.net test.osgeo.net.
