 # Wordpress SOPs
+
+## Updating wordpress to next release
+
+As wordpress is deployed by Ansible, we also have an 'ad-hoc' ansible task to rollout upgrades.
+To do this, it's using the `wp_release` ansible variable, that corresponds to the [wordpress version](https://wordpress.org/download/releases/) to download and unarchive.
+
+If you need to update the deployed plugins, update also in ansible inventory the `wp_plugins` list to reflect new versions of the plugins to be updated.
+
+We want to first validate a successful upgrade on the `dev` instance, available on https://blog.dev.centos.org and then proceed with the `prod` one later.
+
+PS: you need `administrator` right to then be able to visit the /wp-admin/update-core.php
+
+So edit the ansible inventory/host_vars section with new value and then launch the ad-hoc task:
+
+```
+ ansible-playbook-dev playbooks/adhoc-upgrade-wordpress.yml 
+

+
+Once it's done, just ensure to visit <url>/wp-admin/update-core.php and then verify the results.
+If it's all working fine, you can then proceed with the `prod` instance.
