CTVS Texas Exchange 2016 to Exchange 2019 Migration
Industry: Healthcare
Service: Microsoft Exchange Migration/Upgrade

Introduction
Cardiothoracic and Vascular Surgeons (CTVS) Texas are specialists in surgery of the heart, lungs, chest, esophagus and major blood vessels of the body. They are based in Austin, Texas, and have more than 60 years of experience.
This situation creates several challenges:
- Potential downtime or data loss: Migrating such a large volume of mailboxes requires careful planning and execution. Without proper resources, the risk of encountering downtime or data loss during migration increases.
- Delayed project timeline: Jimmy’s solo effort will likely extend the migration timeline, impacting CTVS Texas’s ability to leverage the benefits of Exchange 2019.
- Increased IT burden: Jimmy’s divided focus between migration and daily tasks can lead to inefficiencies and potential neglect of other IT priorities.
‘’Initially I contacted Team Venti and Andy Sanchez reached out to schedule a call with me to discuss our goals, the requirements, and lay out a plan. He explained step by step for us to understand what needed to be done on their and our end.’’ – Jimmy Nguyen, IT administrator at CTVS Texas (2024).
Team Venti’s solution proposition
Our team proposes a comprehensive solution to address CTVS Texas Exchange migration challenges. Our services encompass:
- Migration planning and execution: We handle the entire migration process, from pre-migration planning and mailbox preparation to data transfer and post-migration support. This frees Jimmy to focus on his core IT responsibilities.
- Leveraging best practices and migration tools: Our team leverage proven migration methodologies and industry-standard tools to ensure a smooth and efficient transition to Exchange 2019.
- Minimized downtime and data loss: We prioritize minimizing disruption to CTVS Texas’s operations by implementing a well-defined migration strategy with minimal downtime. Our risk mitigation procedures safeguard data integrity throughout the process.
- Knowledge transfer/training (optional): We can provide Jimmy with knowledge transfer sessions on the new Exchange environment, empowering him to manage it effectively post-migration.
Alternatives considered
- Migration to Exchange Online: CTVS Texas explored migrating to Exchange Online, a cloud-based solution from Microsoft. While this option offered potential cost savings in the long run, they opted for an on-premises upgrade due to immediate budgetary constraints.
Choosing to stay on-premises with Microsoft Exchange Server 2019
- Cost savings (short-term): Upgrading to Exchange 2019 on-premises provided a more cost-effective solution for CTVS Texas in the immediate term, aligning with their current budget plan.
Risk consideration and mitigation
‘’The clinic is not headed into that direction yet, staying in Exchange 2019 will save us money for now, while we plan and get ready to move to the cloud’’ – Jimmy Nguyen, IT administrator at CTVS Texas (2024).
Project timeline


- Discovery call: Andy Sanchez conducted the initial call with Jimmy Nguyen to understand CTVS Texas’s needs and gather migration details.
- Technical consultation: Following the discovery call, George Fam, our senior Exchange engineer, scheduled a technical consultation with Jimmy to delve deeper into the technical aspects of the migration. This collaborative session ensured a smooth and efficient migration plan.
