I have upgraded my Magento from 2.2.7 to 2.3.3. But now, my Magento has so many issues. Is there any way to downgrade Magento 2.3.3 to 2.3.1 or 2.3.2?
Yes you can revert it back to Magento 2.3.1 or 2.3.2, Basically you need to just run following commands on command line.
For Version Magento 2.3.1
composer require magento/product-community-edition 2.3.1 --no-update composer update
For Version Magento 2.3.2
composer require magento/product-community-edition 2.3.2 --no-update composer update
For Version Magento 2.3.3
composer require magento/product-community-edition 2.3.3 --no-update composer update
Then run all the commands upgrade/static content deploy / di compilation and clear cache
downgrade = lots of security issues, database trashing, possible code mess, even more different problems.
if you have only production server - correct way is to create a backup before upgrade, then just jump back.
but if you dont have any backups, then fix all the issues - it will be much cleaner and easier to maintain later.
mashing code back and forth is a bad way.
