Hello @ NeroAdvents Yes. I solve the issue. I've contacted web development agency and they fix it.

@ Johan G PS 1.6 is better than 1.7 I did not face any server migration issues with PS 1.6

They said they set same. They migration another Prestashop site from old server to new server and its working correctly. That is running on PrestaShop™ 1.6.0.14 Only issue with PrestaShop v 1.7.4.2 running website.

I've tried to change "There are not enough products in stock" to "Out of stock" using Prestashop 1.7.4.2 Back Office with "Translation" option. But that was not successful. I did this on PS 1.6 and changed " This product is no longer in stock. " to "Out of Stock" successfully.
