## Data Serialization Mismatch

Data serialization mismatch occurs when the format in which data is stored in the old smart contract differs from the format expected by the new contract. During migration, data must be read, serialized, and then deserialized into the new storage structure.

If the new contract interprets the bytes incorrectly, the stored values, such as interest rates or collateral ratios, will be corrupted. This can lead to incorrect liquidations or the inability to withdraw assets.

This issue is common when moving between different versions of Solidity or when changing data types to optimize for gas. Careful planning of the serialization logic and extensive testing of data migration scripts are required to prevent this type of corruption.
