Introduction
This document details the functional specifications for the project "Test Republic Bank - Connor" aimed at installing Temenos' Transact core banking product and integrating it with Test Republic Bank's legacy mainframe banking system.
Purpose
The purpose of this FSD is to provide a comprehensive description of the functional requirements, data requirements, user interface requirements, non-functional requirements, and other critical project elements to ensure a successful migration and implementation of Temenos' Transact core banking product.
Scope
The scope of this FSD includes the migration of account information from the legacy mainframe banking system to Temenos' Transact, ensuring continuous account access during the transition, integration with third-party software, automated testing, and specific UI design requirements.

Overview
The project aims to migrate Test Republic Bank's account information from a 30-year-old COBOL-based mainframe system to a cloud-based SaaS solution using Temenos' Transact product. The migration must ensure no disruption to client access and integrate with third-party systems for payments and loan origination. The project is scheduled to go live on New Year's Eve, 2025.
