7. Database Migration Service

8. Why do we need Database Migration Service (DMS)?
Focus of Discussion
SQL Server 2008/R2 end
of support
Lift-and-shift to PaaS
with Azure SQL
Database Managed
Instance (MI)
Move to IaaS with
Azure SQL VM
SQL DB MI is compatible with versions as far back
as SQL Server 2005; no more future upgrades or
patches required as SQL DB will always run on the
latest feature as part of fully managed services
Upgrade to SQL Server 2017 on Azure VMs, or
Move “as-is” with SQL Server and Windows
Server 2008/R2 and get 3 years of Extended
Security Updates* for free
Upgrade to SQL Server 2017** (and
Windows Server 2016) or stays “as-is” at 2008 and
purchase Extended Security Updates
Modernize to Azure
Modernize on premises
