How to upgrade drupal
The drupal upgrade process is similar in spirit to the upgrade process for wordpress.
Back up the database
mysqldump --verbose -u USER -pPASSWD masspirate_drup | gzip -9 > ~/masspirate_drup.$(date +%F).sql.gz
replacing USER and PASSWD with appropriate values.
Make sure all files are checked in
$ git status # On branch master nothing to commit (working directory clean)
drush pm-update --no-core
After upgrading, do git status and git add or git rm changed (removed) files, then
git commit git push origin git remote update git merge origin/master
MF/PL's infrastructure handles updates to drupal core.
For civicrm upgrades, I've found
$ drush help | grep civicrm-upgrade civicrm-upgrade Replace CiviCRM codebase with new specified tarfile and upgrade civicrm-upgrade-db Execute the civicrm/upgrade?reset=1 process from the command line.
this seems promising, and I plan to try it the next time we need to upgrade civicrm.
