Can we directly upgrade the Magento 2.1.5 to 2.3? Magento 2.1 supports the PHP version 5.6, 7 & 7.1 only and Magento 2.3 supports 7.1.3,7.2,7.3. Both support the different versions while readiness checks it always raised an error “requires PHP ^7.1.3 -> your PHP version (7.0.6) does not satisfy that requirement”.
Anyone, can you please let me know the process of how to upgrade Magento 2.1 to 2.3. I am running this on my local window machine.
