hi
In order to determine the cause of the issue, I would need more information about the migration process, such as what specific steps were taken during the migration and if any errors were encountered. Additionally, I would need to see the relevant code for the PayPal and Square integration, as well as any error messages that are currently being displayed.
It is also important to check the payment gateway's API credentials, SSL certification and the version of symfony you are using, as these are all common causes of integration issues.
Please note that the issue might be related to the server's environment, so you may want to check the server's configurations and PHP version
please knock me i can solve this within short time
thanks
