Here, the old code means Magento2.3.4, and the new code means magento upgraded v2.4.4-p2.
Recently, I upgraded a site from Magento 2.3.4 to v2.4.4-p2, and I have much customization.
Does Magento work with upgraded site v2.4.4-p2 and old site v2.3.4 with the same database?
Magento 2.3.4 is compatible with PHP7.2 to 7.3 and composer version 1, while Magento 2.4.4-p2 is compatible with PHP8.1 and composer version 2.
I would like to be able to switch back and forward between the 2.3.4 and 2.4.4-p2 versions using the same DB.
Can we point the same database to different magento v2.3.4 and v2.4.4-p2? Will it cause any problems?
Both magento versions have different servers.
Please give any suggestions or ideas.
Thanks
