I have a client who needs to upgrade from Magento 2.2 to Magento 2.4.2. Initial estimates from the Magento partner managing the site are in the range of 10-12 weeks (man days). Can anyone share their experience and how this figure might be realistic? It seems very high.
Thanks and regards
Upgrading from Magento 2.2 to 2.4 sometimes challenging. We usually say major version upgrade.
So there are chances the time they suggested is ok in terms of days.
In terms of estimation, I can't say for sure, how much they are charging.
You can try to reach out to other agencies too to understand the process and estimates.
Upgrade Magento Version from 2.3.X to 2.4.0
Step 1: If you are directly performing the upgrade on your live site then first put your site into maintenance mode by running below command.
php bin/magento maintenance:enable
Step 2: If you are performing the upgrade on your local system then you can skip step 1 and start with step 2.
Take a backup of the composer.json
cp composer.json composer.json.bak
Step 3: Install the Composer update plugin
composer require magento/composer-root-update-plugin=~1.0 --no-update
Step 4: Update composer.json file with latest version. In our case, it is Magento Version 2.4.0. Navigate to your Magento 2 installation root path and run below command
composer require magento/product-community-edition=2.4.0 --no-update
Step 5: Run below command
This command will take some time to finish. This command will actually download all the required packages and upgrade your Magento version from 2.3.x to 2.4.0. After this command finish, run below commands
Step 6: Clear cache and regenerate code.
php bin/magento cache:clean
rm -rf var/cache/*
rm -rf var/page_cache/*
rm -rf generated/code/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
Step 7: Disable maintenance mode
php bin/magento maintenance:disable
I recommend you to contact this Landofcoder Company for check with them.
