@Jersen Mathew Thank you for reaching out.
My understanding is that you are looking to migrate your dynamics 365 business central application which is configured with Azure SQL Database single server to an elastic pool database.
You can use an Azure SQL Database Elastic Pool with the latest version of Business Central. To use an Elastic Pool with Business Central, you will need to create the Elastic Pool and then migrate your existing Azure SQL Database to the pool. You can then configure Business Central to use the Elastic Pool as its database.
New and Planned for Dynamics 365 Business Central
Dynamics Business Central as a service on Azure
