Maintenance

Sometimes we offer our clients a maintenance service in which we are responsable of keeping WP and the plugins used on the site up to date.

Onboarding

When a client signs up for the maintenance plan, a plugin list is made, and the critical ones are marked as such. This list helps us know which plugins needs special treatment or alerting when an update is available for them.

Every plugin on this list should have a short description of it’s purpose on the site, and a short test case about how to test it’s functionality.

For plugins that are critical to the functionality, we need to have the devs contact channels handy (support channels), and find at least one alternative plugin in case it breaks during the update, and the devs fail to provide an update/fix in a short period of time. In the case it’s needed, this alternative will be offered to the client, and he must accept to install this and replace the old plugin.

This list should be compiled with the dev team that worked on the project before, and/or with the client itself, who probably know more about why they use the plugins they use (unles we started the site from the scratch).

After it’s finished it’s then attached to a card in the Assets column of the Maintenance board in our Breeze, along with other details, like:

Execution

When the schedule time comes, the maintenace agent (you) needs to do the following:

After these things have been checked, do the following (always in staging first):

  1. Create a backup of the staging enviroment (if possible, depending on hosting)

  2. Make sure that staging is a fresh copy of the codebase from production (plugins, themes, settings, etc).

  3. Migrate any licenses that might be needed in order to update (eg: WooThemes licenses) to staging. This is usually known by us in the project board. If that’s not the case, just contact the Tech Contact on the client side and ask them to activate the licenses in the staging enviroment so we can update.

    Note: If the client is ok, these licenses should be saved in the project board for future reference.

  4. Make a list of plugins that have an update, and report that to the Main Dev of the project. He/She should be able to see if some of the plugins with updates are going to create conflicts with our work there.

  5. After this, there can be two outcomes:

Conflicts found with our code

  1. If the Main Dev warned about conflicts, you’ll update the plugins, and ask the Main Dev to see if everything still works, or to fix any issues you may already have found.

  2. After that, the Tech Contact from the client should also run tests over their normal workflows (eg: purchase funnels for different products if eCommerce), and also pay special attention to workflows that are most likely to be affected by the updated plugins (as reported by the dev team).

  3. There will probably be a bit of back and forth between the dev team and the client until everything is back on track and working.

    Note for Devs: Any update made, needs to be made in such way that if possible it can be deployed before the updates are applied in production, and so that the code still works before the update. This is to avoid any downtime between the plugin update and the fix deployment.

  4. After everything is working in staging, the updates need to be applied again in production (NOT pushed), and any updates made by the dev team needs to be deployed as well.

  5. This should be the end of the current maintenance cycle.

No conflicts found with our code

This doesn’t mean that there won’t be problems, it just means that this is usually not problems that we can anticipate from a Dev perspective.

  1. You’ll update plugins, and take a quick look yourself at the site (no white pages, site seems to still be operational).

  2. Ask the customer to overview their normal workflows (purchase funnels, as detailed above).

  3. If there’s no problems apply the updates in production, and that’s it for this cycle.

  4. If there is some issues reported by the customer, then the dev team needs to be called in and quote the fix for the problem.

    Note for Devs: Any update made, needs to be made in such way that if possible it can be deployed before the updates are applied in production, and so that the code still works before the update. This is to avoid any downtime between the plugin update and the fix deployment.

  5. After the fix is done by the dev team, and it’s ready to be deployed, the changes from the dev team are deployed, and then the plugin updates are applied in production.

  6. And that’s it for the maintenance cycle.

Testing/QA

Testing of WP major releases (4.x or x.0) should start early on in staging, from the RC releases. These versions are usually available a couple weeks before the final release, meaning that there’s time to do it in between 2 cycles (for monthly maintenance clients).

As explained above there are several people involved in testing:

After all these testing barriers have been passed, we think it’s safe to say that the updates are safe to be deployed (re applied manually) to production. If some error pops up, we already had the client verify the site before deploying, so we can be excused of any errors that was missed during testing.
