Upgrading WordPress 3.2.1

So this is the journey to update WordPress 3.2.1 to 5.3

I’ve taken a copy of the site and set it up on a temporary URL and set the following within wp-config.php

define('WP_HOME','http://test.site.com');
define('WP_SITEURL','http://test.site.com');

I’ve also had to drop the PHP version to 5.6 to be able to run the site.

Step 1 – Getting to a wp-cli capable version 3.2.1 to 3.7

So I’d like to use wp-cli, and increment the installation a bit in the 3.x branch just to see how well it goes.

Grab wp-cli version 1.3.0 at https://github.com/wp-cli/wp-cli/releases/download/v1.3.0/wp-cli-1.3.0.phar

There is no available download on wordpress.org for 3.7, at least one that isn’t listed. So if you simply grab a download link for any older version from their release page you can change the version number in the file name.

Here’s WordPress 3.7 zip installer https://wordpress.org/wordpress-3.7.zip

Upgrade WordPress Manually using these instructions https://wordpress.org/support/article/updating-wordpress/#manual-update

Since I have SSH access I’m going to do it the following way. The below commands assume public_html is your directory root where your WordPress installation sits.

wget https://wordpress.org/wordpress-3.7.zip
mv public_html to public_html.old
unzip wordress-3.7.zip -d public_html
rm -rf public_html/wp-content
cp public_html.old/wp-config.php public_html
cp public_html.old/wp-content public_html

Go to your sites /wp-admin page and update the database.

Step 2 – Upgrade 3.7 to 4.0 because why not?

So I just choose 4.0 because it seems far enough ahead but not too far.

I’m going to first test my custom wp-cli and see if I can upgrade to 3.7.31

php5.6 /usr/local/bin/wp-cli-1.3.0.phar --allow-root core update --version=3.7.31
Updating to version 3.7.31 (en_US)...
Downloading update from https://wordpress.org/wordpress-3.7.31.zip...
Unpacking the update...
Cleaning up files...
No files found that need cleaned up.
Success: WordPress updated successfully.

Success, so now let’s bump the version up to 4.0

php5.6 /usr/local/bin/wp-cli-1.3.0.phar --allow-root core update --version=4.0
Updating to version 4.0 (en_US)…
Downloading update from https://wordpress.org/wordpress-4.0.zip…
Unpacking the update…
Cleaning up files…
No files found that need cleaned up.
Success: WordPress updated successfully.

You’ll need to login to your sites /wp-admin and run the database updates if there are any.

You’ll also want to confirm that your site is still displaying properly. You might find that your theme isn’t supported by WordPress 4.0

You might also need to upgrade PHP at some point, however WordPress supports 5.6 all the way up to WordPress 5.3

Step 3 – Upgrade to 5.3! Let’s do it!

So I don’t really need to use the old wp-cli v1.3.0 and can use the latest version since we got up to WordPress 4.0

wp --allow-root core update
Updating to version 5.3 (en_US)...
Downloading update from https://downloads.wordpress.org/release/wordpress-5.3-new-bundled.zip...
Unpacking the update...
Cleaning up files...
No files found that need cleaning up.
Success: WordPress updated successfully.

Luckily for me, there were no issues!

Creators Of Mobile Chat For the iPhone Twenty08 Hires AplloIM Developer

If you bought the iPhone when it first came out, you had two choices for Instant Messaging. Twenty08's MobileChat and Alex Schaefer's ApolloIM. Twenty08 has now hired Alex Schaefer to work exclusively on MobileChat
twenty08 would like to formally welcome aboard…Alex Schaefer. Many of you may know him as the founder of the world’s first Native iPhone IM Application, ApolloIM. ApolloIM was an amazing application and during it’s run, MobileChat and Apollo stood head to head and constantly battled to create the better app. (Friendly war of course!) The best part about it was that no one won! Only our respective users benefited from the friendly competition, and you can’t ask for anything better than that as far as I’m concerned. Now with Alex working on our side, we believe that MobileChat will be able to rise up and regain its glory as the number one iPhone application that we all know it can be. He is a very talented developer (plus a great guy) who has already brought some great ideas to the table and we’re all very excited to see our new-found relationship grow.
