A Solutions Architect needs to determine which AWS services can be used to perform the migration while minimizing the amount of work and time required.Which of the following will meet the requirements?
A.Use AWS SCT to generate the schema scripts and apply them on the target prior to migration. Use AWS DMS to analyse the current schema and provide a recommendation for the optimal database engine. Then use AWS DMS to migrate to the recommended enginer.Use AWS SCT to identify what embedded SQL code in the application can be converted and what has to be done manually. B.Use AWS SCT to generate the schema scripts and apply them on the target prior to migration. Use AWS DMS to begin moving data from the on-premises database to AWS.After the initial copy continue to use AWS DMS to keep the databases insync until cutting over to the new database. Use AWS SCT to identify what embedded SQL code in the application can be converted and what has to be done manually. C.Use AWS DMS to help identify the best target deployment between installing the database engine on Amazon EC2 dierctly or moving to Amazon RDS. Then use AWS DMS to migrate to the platform. Use AWS Application Discovery Service to identify what embedded SQL code in the application can be converted and what has to be done manually. D.Use AWS DMS to begin moving data from the on-premises database to AWS. After the intitial copy continue to use AWS DMS to keep the databases in sync until cutting over to the new database. Use AWS Application Discovery Service to identify what embedded SQL code in the application can be converted and what has to be done manually.正确答案B
