Upgrading Mag 2.3 to 2.4

[PawelP]

Hi Craig,

I know you get to this but can you please tell me in short how to upgrade Mag from 2.3 to 2.4

My current server: ubuntu 18.04, php7.3,21 MySQL 5.7.31, ElasticSerach 7.6,

I’m guessing I need to start with upgrading my PHP to 7.4 runnings:

sudo apt-get install php7.4 libapache2-mod-php7.4 php7.4-mysql php7.4-soap php7.4-bcmath php7.4-xml php7.4-mbstring php7.4-gd php7.4-common php7.4-cli php7.4-curl php7.4-intl php7.4-zip zip unzip -y

Then I need to upgrade my SQL to 8.0. Can you please give me a tip on to do it?

Update my “date.timezone" in php.ini. This is something new for Mag 2.4.

And finally upgrade my magento with the following:
(This procedure was for upgrading Mg 2.3. to 2.3.4 but I may work )

bin/magento maintenance:enable
composer require magento/product-community-edition=2.4.0 --no-update
composer update
bin/magento cache:clean
rm -rf var/cache/* var/page_cache/* generated/code/*
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy en_US -f
bin/magento cache:clean
bin/magento maintenance:disable

Upgrade Ubuntu

Upgrade OS from old to latest with:

sudo apt update
sudo do-release-upgrade

You may need to do sudo apt update after to update the Repos of the new OS.

Upgrade PHP

Install necessary modules (don’t forget php7.4-gettext for phpMyAdmin)

sudo apt-get install php7.4 libapache2-mod-php7.4 php7.4-mysql php7.4-soap php7.4-bcmath php7.4-xml php7.4-mbstring php7.4-gd php7.4-common php7.4-cli php7.4-curl php7.4-intl php7.4-zip php7.4-gettext zip unzip -y

Then update new config files

sudo nano /etc/php/7.4/apache2/php.ini

Switch to new PHP version and confirm (Method 1)

sudo a2dismod php7.2
sudo a2enmod php7.4
systemsctl restart apache
php -v

If PHP version does not update, do this (Method 2)

sudo update-alternatives --config php

Upgrade MySQL

This might work ok but really not sure. I have a feeling that I ran into issues doing this in the past due to some conflict. But who knows…

sudo apt upgrade mysql-server

Upgrade phpMyAdmin

Update phpMyAdmin to be compatible with latest MySQL and PHP upgrades

sudo apt upgrade phpmyadmin

Upgrade Elasticsearch

Yet to research…

Upgrade Magento
