Systems and methods for multi-domain application hosting platform migration

A method for migrating functionalities of a first hosting platform associated with a service provider to a second hosting platform associated with the service provider, wherein the first hosting platform is configured to provide transaction services to user computing devices in a plurality of domains via an electronic communication network, wherein each domain in the plurality of domains is associated with a distinct online service provided by a distinct application of the first hosting platform, wherein a platform testing system is configured to test and validate the functionalities in the second hosting platform by shadow testing the second hosting platform across the plurality of domains over a period of time, and wherein the method comprises:

• monitoring, by one or more hardware processors associated with the platform testing system, responses from the first and second hosting platforms during processing transaction requests across the plurality of domains;
• determining, by the one or more hardware processors and based on the responses from the first and second hosting platforms, a set of validation criteria for validating the functionalities in the second hosting platform across the plurality of domains, wherein the set of validation criteria comprises at least one critical validation criterion and at least one non-critical validation criterion;
• storing the set of validation criteria in a data storage;
• providing, by the one or more hardware processors associated with the platform testing system, a user interface that enables designated users with domain knowledge to modify the set of validation criteria;
• generating, by the one or more hardware processors, a correlation table for modifying transaction requests for the second hosting platform based on the modified set of validation criteria and the past responses generated by the first and second hosting platforms, wherein the correlation table comprises a mapping between first request attribute values associated with the first hosting platform and second request attribute values associated with the second hosting platform;
• storing the correlation table in the data storage;
• intercepting, by the one or more hardware processors, a first transaction request associated with a first domain in the plurality of domains and intended for the first hosting platform;
• determining, based on the correlation table, whether a modification to the first transaction request is required to test a functionality associated with the first transaction request in the second hosting platform;
• in response to determining that the modification to the first transaction request is required, generating, by the one or more hardware processors, a second transaction request based on the first transaction request and the correlation table, wherein the generating the second transaction request comprises modifying the first transaction request based on a record in the correlation table;
• transmitting the first transaction request to the first hosting platform;
• transmitting the second transaction request to the second hosting platform;
• receiving, from the first transaction processing system, a first response for the first transaction request;
• receiving, from the second transaction processing system, a second response for the second transaction request;
• comparing the first response against the second response;
• determining whether the second response satisfies a subset of the set of validation criteria corresponding to the first domain;
• reporting, on a user computing device, data indicating a result of the comparing;
• and
• determining whether to validate the functionality of the second hosting platform based on the result of the comparing, wherein the platform testing system is configured to continue validating the functionalities across the plurality of domains in the second hosting platform based on the shadow testing of the second hosting platform over the period of time.

A non-transitory machine-readable medium having stored thereon machine-readable instructions usable for migrating functionalities of a first hosting platform associated with a service provider to a second hosting platform associated with the service provider, wherein the first hosting platform is configured to provide transaction services to user computing devices in a plurality of domains via an electronic communication network, wherein each domain in the plurality of domains is associated with a distinct online service provided by a distinct application of the first hosting platform, wherein a platform testing system is configured to test and validate the functionalities in the second hosting platform by shadow testing the second hosting platform across the plurality of domains over a period of time, and wherein the machine-readable instructions are executable to cause a machine associated with the platform testing system to perform operations comprising:

• monitoring responses from the first and second hosting platforms during processing transaction requests across the plurality of domains;
• determining, based on the responses from the first and second hosting platforms, a set of validation criteria for validating the functionalities in the second hosting platform across the plurality of domains, wherein the set of validation criteria comprises a critical validation criterion and a non-critical validation criterion;
• storing the modified set of validation criteria in a data storage;
• providing a user interface that enables designated users with domain knowledge to modify the set of validation criteria;
• generating a correlation table for modifying transaction requests for the second hosting platform based on the modified set of validation criteria and the past responses generated by the first and second hosting platforms, wherein the correlation table comprises a mapping between first request attribute values associated with the first hosting platform and second request attribute values associated with the second hosting platform;
• storing the correlation table in the data storage;
• intercepting a first transaction request intended for the first hosting platform, wherein the first transaction request is associated with a first domain of the plurality of domains;
• determining, based on the correlation table, whether a modification to the first transaction request is required to test a functionality associated with the first transaction request in the second hosting platform;
• in response to determining that the modification to the first transaction request is required, generating a second transaction request based on the first transaction request and the correlation table, wherein the generating the second transaction request comprises modifying the first transaction request based on the correlation table;
• transmitting the first transaction request to the first hosting platform;
• transmitting the second transaction request to the second hosting platform;
• receiving, from the first hosting platform, a first response for the first transaction request;
• receiving, from the second hosting platform, a second response for the second transaction request;
• determining a difference between the first response and the second response;
• determining whether the difference satisfies a first subset of the set of validation criteria corresponding to the first domain;
• reporting, on a user computing device, information indicating the difference;
• and
• determining whether to validate the functionality of the second hosting platform based on the determining whether the difference satisfies the first subset of the set of validation criteria, wherein the platform testing system is configured to continue validating the functionalities across the plurality of domains in the second hosting platform based on the shadow testing of the second hosting platform over the period of time.
