Migrating a large SVN repository (around 1.4TB) to Git can be complex and challenging due to the size and data involved. Such a migration requires careful planning to preserve history, maintain data integrity, and handle large volumes of data efficiently. You need to choose the right tools and strategies, such as breaking down the migration into smaller parts or using specialized migration tools that can handle big data sizes. Additionally, it’s essential to consider the hardware requirements, potential cleanup before migration, and testing afterward to ensure accuracy and completeness.
