Role and Responsibilities: As the project lead, I collaborated closely with the systems administrator to ensure the new server was configured correctly with the appropriate operating system and corresponding SQL version. My responsibilities included:
Planning and coordinating the migration process.
Setting up the new server environment.
Ensuring compatibility between the old and new database systems.
Conducting tests to verify data integrity post-migration.
Technologies and Tools Used:
Windows Server 2012 R2
SQL Server (latest version)
Data migration tools
Scripting languages (e.g., PowerShell)
Testing and monitoring software
Challenges and Solutions: One major challenge was ensuring minimal downtime during the migration process. To address this, we implemented a phased migration approach and conducted thorough pre-migration testing to anticipate potential issues. Additionally, we developed a rollback plan to mitigate risks.
A specific issue we encountered was the dependency on certain accounts remaining active until data could be offloaded to other accounts. Some of these accounts belonged to former employees, and the passwords were no longer available. To overcome this, I wrote scripts to copy over all accounts regardless of password status, ensuring that the data remained intact and accessible.
Key Outcomes:
Successful upgrade of the database server with minimal downtime.
Improved database performance and security.
Enhanced scalability for future growth.
Streamlined data management processes.
Maintained data integrity and access despite account credential issues.
