by Raghu on December 21, 2009

If you are planning to upgrade wordpress to latest release, do the following

  1. Read Worpdress Support forums to see any upgrade problems
  2. Backup Entire Database
  3. Check for Minimum Requirements ( MySQL, PHP)
  4. Check if all installed plugins supports the latest version of wordpress.
  5. Deactivate all the plugins
  6. Know how to revert to previous wordpress version, if upgrade were to fail.
  7. Test the upgrade in local wordpress installation ( if downtime of site might be major issue)
  8. Perform WordPress Upgrade
  9. Upgrade WordPress Database if required
  10. Check if Site is up and running.
  11. Click on few links to to check if URL structure is maintained.
  12. Activate the supported plugins one at a time.

WordPress 2.8.6 to 2.9 upgrade created couple of problems. It was because

  • Some of the plug-in’s didn’t support 2.9
  • db_version in Table WP_Options had incorrect value.

After I fixed the db_verison, site was up and running, but all the url was broken. It was due to unsupported some plug-in in 2.9
