B: Ensure all user accounts and privileges are compatible with MySQL 8.0:
* MySQL HeatWaveis based onMySQL 8.0, so compatibility is crucial.
* User accounts and privileges must be updated to match the security and syntax requirements of MySQL
8.0.
* If any incompatibility is detected, the accounts should be recreated on the target HeatWave instance.
* Typical issues include changes inpassword hashing algorithms,privilege structure, androle management.
Why the other options are incorrect:
* A. Resetting passwords to default:Risky from a security perspective and unnecessary.
* C. Deleting user accounts except root:This drastically limits access and disrupts database operations.
* D. External authentication (LDAP):Not mandatory or relevant to compatibility with HeatWave.
* E. Merging accounts into a single 'admin':Violates best practices for user management and security.
