This page describes the available migration preferences for Microsoft SQL
Server database deployments.
Cloud SQL for SQL Server settings
Migration Center lets you choose Cloud SQL as the target database
deployment for your database.
From the MS SQL version type list, select the version type to which you
want to migrate.
From the Sizing method list, select the sizing strategy
that you want to apply during the migration. If you select Utilization
based, Migration Center uses performance metrics from your
database, if available, to provide sizing recommendations.
Availability
Specify how to distribute your database across Google Cloud zones.
From the Zones list, select either Single zone or Multiple zones.
Choosing multiple zones for your database provides a backup zone
in case the primary zone becomes unavailable.
For more information about region-specific considerations, see
Geography and regions.
Multithreading
By default, multithreading is enabled on Cloud SQL databases.
To save on costs, you can choose to disable simultaneous multithreading.
This might reduce the performance of your database.
Specify your preferred pricing track for the database that you migrate to
Google Cloud.
Choose between on demand pricing, or a committed use of
one or three years.
Committed use discounts (CUDs) apply when you choose a committed use,
and appear in your total cost of ownership (TCO) report.
