1. Check versions and business dependencies
To update WordPress safely, identify the current CMS, theme, plugins and PHP version, then check compatibility with the proposed versions. WordPress documentation describes updating core; plugin and theme requirements also need review. A store can depend on payment extensions and scheduled jobs that are not visible on the homepage. Decide which workflows must pass after the change.
2. Prepare backups and a maintenance window
Back up files and the database and confirm how they would be restored. Use a staging environment where available, and avoid sending real customer notifications from that copy. Agree when changes will happen and who can authorize a rollback. If an old extension has no supported update, investigate replacement rather than treating a backup as permission to ignore incompatibility.
3. Update, verify and record the result
Apply the agreed updates in a controlled sequence and review errors. Check key pages, login, enquiry delivery and store behavior where applicable, including the receiving system. Use sandbox payments or an authorized test order. Keep a version record and note remaining issues. Passing these checks gives evidence for the tested workflows, not a guarantee against every defect.
Use an update go or no-go check
Updates need an inventory of themes, plugins, custom code and external dependencies. Backups must include the required assets and a plausible restore path. Staging helps but may not reproduce payment, mail or production data conditions.
- Record versions and release dependencies.
- Confirm backup access and recovery plan.
- Test representative workflows in a suitable environment.
- Stop on unexplained failures and document the next action.
Go or no-go checks for customer workflows
WordPress recommends backups before updating. Record component, version before/after, checks and exceptions. Do not click through multiple failures or assume a rollback reverses database migrations. Unsupported plugins and custom-code repairs need a separate decision.
| Journey | Test | Stop condition |
|---|---|---|
| Enquiry | Message reaches destination | Missing delivery |
| Checkout | Authorized order/payment/notification | Incorrect order state |
| Scheduled job | Expected completion | Unexpected errors |
Example: rollback when new orders already exist
An update fails after new orders arrive. Replacing the whole database with an older copy would lose those orders, so recovery must account for changes since the backup. This is an illustrative scenario, not a customer case or a promised result.
