Data migration

System Fundamentals

When we move data from one system to another we transfer it. However, when you aim to permanently move data (most commonly when you are building a new system), we can say you are migrating data. Please know this is almost always a deliberate process.

The list below is used with gratitude from the Dartford Grammar School . The list represent types of problems we can encounter when we migrate data:

• Incompatible file formats
• Data structure differences
• Validation rules
• Incomplete data transfers
• International conventions on dates
• Currencies & character set

Standards

• Discuss problems that may arise as a part of data migration.

Give a sequence of brief answers with no explanation.

Offer a considered and balanced review that includes a range of arguments, factors or hypotheses. Opinions or conclusions should be presented clearly and supported by appropriate evidence.
