I wanted to know is it possible to update Magento from 2.2.5 to 2.3.1? Or what is a solution to update all Magento 2.2.5 stores to Magento 2.3.1? If we will update it then what are the challenges for that we have to be prepared?
Please let me know if there any solution for this or not. REF - How to Upgrade magento version from 2.2.X to 2.3.0?
Conclusion: don't install symfony/console
&magento/product-community-edition 2.3.0 requires magento/framework 102.0.0
when upgrade via composer.
