We have a few databases in Pricing Tier: Basic
, S0
... like below picture:
These databases were created before a new Elastic Pool is created. Now we want to move these databases into Elastic Pool for costing saving. But it seems I don't know how to move them on the Azure portal.
Instead of being applied to a single database, an eDTU applies to a pool of databases that share resources in an elastic pool, measuring the performance potential of the entire pool instead of a single database. Each database in the pool is capable of using a few or lots of the entire pool's performance capacity.
Azure SQL Elastic Pool lets us under-provision system resources between a group of SQL databases to save cost at a satisfactory performance level. This is more effective if you add more databases to the Elastic Pool.
In the Azure portal menu, select All services. Search for and select Azure Database Migration Services. On the Azure Database Migration Services screen, select the Azure Database Migration Service instance that you created. Select New Migration Project.
Extra storage for an elastic pool can be provisioned by increasing its max size using the Azure portal, PowerShell, the Azure CLI, or the REST API. The price of extra storage for an elastic pool is the extra storage amount multiplied by the extra storage unit price of the service tier.
Fast answer if don't want to read any link, you just want do OP asked:
⚠ Take in mind that all databases you want to add to the pool should be in the same Server than the pool.
You can create an elastic pool in the same server as your databases, through portal using instructions here - https://azure.microsoft.com/en-us/documentation/articles/sql-database-elastic-pool-create-portal/
Once you have created a pool, you can add existing databases to the pool using instructions here - https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-pool#manage-an-elastic-pool-and-its-databases
