Updating to wordpress 2 7
The only way to truly know what has changed with the plugin or theme is to read the change log.2.0 – This is a major version upgrade from 1.0 and will likely be entirely different from the original plugin.
Backup, read the documentation, and upgrade with caution and spare time on your hands.2.1 – This is an update to the major version.
Many people offer maintenance plans to help you stay up to date.
The problem with some of these plans is that they offer weekly, monthly, or quarterly updates.
Even deactivated themes and plugins can leave your system vulnerable.
Following are best practices for keeping your site up to date.
The longer you wait to update, the harder it will be. Changes might be made to templates and how data is stored in the database that are more easily managed in increments.
Also, more importantly, updates can be critical for security.
Pretty soon, all of these things add up, and the cost of setting these things up manually versus taking advantage of the service makes more sense.
Hackers can immediately write bots to automatically crawl the web and exploit these vulnerabilities.
Outdated themes, plugins, and Word Press version are the number one way hackers gain access to your site (besides brute force hacks of your login).
Create both a FULL SITE (aka Complete) BACKUP as well as a DATABASE ONLY backup. There are many ways you can create a staging environment for your site to test updates without effecting the live site: Ideally, you should keep a perpetual locally hosted copy of the websites you maintain.
Download both of these backups to your local computer. You can run all updates on the local site first then push the updates to the live server (using Git) or repeat the process on the live server. The only variation between your locally hosted Word Press and the server are PHP and My SQL versions.
