A computerized system for API migration. The system includes a memory storing instructions and a processor configured to execute the instructions to perform operations, which include segregating client accounts three groups, assigning a first API for communications with the first group and a second API for communications with the second group, and assigning the first API for communications with a first portion of the third group and the second API for communications with a second portion of the third group. The operations may also include collecting communications from the groups and generating metrics associated with each group, and generating a comparative report and a compatibility report. The operations may also include transmitting at least one of an alert or a recommendation based on the comparative report and the compatibility report.
