On September 1, 2020, WordPress 5.5.1 was released to the public.
Tools We Might Need to Use in This Practice
Backup / Restore plugins
Plugins related to WordPress core
Advanced purpose (You must know what you are doing clearly)
All we need here is the back-end of WordPress without file permissions issue. WP-CLI, SFTP, and other ways through WordPress management services (e.g. ManagedWP, MainWP) won’t be mentioned in this article.

Difference Between Backup and Staging
Backup
Backups are for reverting to a previous version when a problem arises on the site.
For example, you run an update on your website and it causes your site to malfunction. You find that plugins are not compatible with the new version of WordPress. It would take considerable time to update these plugins or find replacements. To solve the issue immediately and get your site back to normal, you can restore your backup.
Backups come in handy when things go wrong such as botched updates, human errors, the presence of malware, and so on.
Pros:
- Could be done manually and automatically(scheduled).
- Could be used specifically and separately from databases, individual plugins, themes, and directories for conditions to all files for the whole website or machine(server level).
- Highly elasticity and handy.
Cons:
- Will affect your live site.
Staging
Staging enables you to create a clone of your WordPress website. This is done specifically for development. You can try out new themes, plugins, designs, and layouts. You can test out updates and even test restore your backup! None of the changes you make will affect your live site.
Pros:
- Won’t affect your live site (live site still might be affected in some cases).
Cons:
- It takes time way more than backup.
- You might need to take care of the modification of the database and files in the staging period in some cases.
Considering the popularity of both of them. We chose Backup for the demo in this article and meetup purposes.
Step 1
Backup
You can choose one of the below methods.
- Run a complete backup.
- Run a complete backup of the website excluding files under
/wp-content/uploads
path. - Run backups through WPVivid individually or skip this, just rely on the Rollback function with WPVivid Pro.

Step 2
Check The Compatibility of Plugins & Themes
Checking, and reviewing changelogs is always a good habit!

(Practice Time)
Step 3
Update plugins & themes that are compatible with WordPress.
Plugins
Anything you’ve activated, but keep in mind the plugins which can be seen their compatibility with WordPress or other main plugins like WooCommerce, page builder (no page builder”s” in one website, OK?).
Theme
Twenty Twenty for example.
Changelog of theme Twenty Twenty
https://wordpress.org/support/article/twenty-twenty-changelog/
Changelogs of themes are much harder to find than plugins. No matter if one is on https://wordpress.org/themes/, Themeforest, or any official website of the themes.
Step 4
Update to WordPress 5.5!
(Practice Time)
Step 5
Check, Check, Check
Or wait for someone to check the website and report to you – Not recommended.
Step 6 ( if necessary )
- Install & activate Enable jQuery Migrate Helper to solve the issue that happened after updating to WordPress 5.5.
- Restore from what backup you’ve got.
- Downgrade WordPress with WP Downgrade.
- Rollback plugins/themes with WPVivid Pro.
- Switch to the WordPress version you like, and restore from a snapshot by WP Reset, and WP Reset Pro.

Final
Happy Ending? Hope So!
There won’t be any real final work for a website you’d like to keep running unless the website is terminated.
So, just keep making it better and better for your purpose.
