Success criteria
What you receive
How the work unfolds
Confirm scope, stakeholders, communication plan, migration objectives, target Azure VM details, anticipated cutover approach, maintenance window expectations, and required access. Identify any application owners, database dependencies, and vendor contacts needed for testing or cutover coordination.
Review the source SQL Server and Windows Server configuration, SQL Server version and edition, database list, database sizes, compatibility considerations, replication eligibility, SQL Agent status, service accounts, backup posture, connectivity to Azure, and required firewall or name resolution paths between Publisher, Distributor, and Subscriber.
Prepare the Azure VM SQL Server target as needed for replication, validate connectivity, configure the transactional replication topology, create the publication and subscription, configure the Snapshot Agent, Log Reader Agent, and Distribution Agent, and initialize the subscriber using the snapshot containing the required schema, data, and published database objects.
Monitor replication health and latency, allow incremental changes to synchronize to the Azure VM SQL Server subscriber, coordinate a final cutover window, quiesce or redirect application writes as appropriate, validate final synchronization, disable replication, and point users or applications to the Azure-hosted SQL Server database endpoint.
Validate database availability from Azure, confirm that expected data is present, review replication and SQL Agent job status, support application or user smoke testing, address migration-related issues identified during validation, and document final status, acceptance evidence, outstanding issues, and budget information in the closeout report.

Limitations & technical notes
Frequently asked questions
What does the SQL Server Migration via Replication to Azure VM service include?
This service migrates a SQL Server to an Azure VM with minimal downtime by using SQL Server transactional replication when an on-premises AlwaysOn deployment is not available. IT Partner implements the Snapshot Agent, Log Reader Agent, and Distribution Agent, prepares snapshot files for published schema and data, synchronizes distribution jobs, and manages incremental changes from the Publisher to the Azure VM Subscriber according to the Distribution Agent schedule.
When is transactional replication the right approach for this Azure SQL Server migration?
Transactional replication is appropriate for this service when you need to minimize downtime and do not have an AlwaysOn on-premises deployment available. It is typically used in server-to-server environments, so IT Partner uses it to keep the Azure VM SQL Server subscriber synchronized before the final cutover.
What is the expected outcome of the migration?
The project success criterion is that SQL databases are available from Azure without data loss. The engagement is considered successful when the Azure VM-hosted SQL Server can serve the migrated databases after replication is disabled and users are pointed to the Azure database.
How much downtime should we expect during the SQL Server migration?
The service is designed to minimize downtime because transactional replication can keep incremental changes flowing from the Publisher to the Azure VM Subscriber before cutover. Exact downtime is not stated in the service scope, so the specific cutover window should be confirmed with IT Partner based on the environment and Distribution Agent schedule.
How long does the SQL Server migration service take?
The listed duration for SKU ITPWW310MIGOT is 1 week. The service notes that the plan may vary depending on your needs, so any environment-specific timing should be confirmed during kickoff and review.
What is the price of this SQL Server migration service?
The listed price for the SQL Server Migration via Replication to Azure VM service, SKU ITPWW310MIGOT, is $800. Any work outside the stated scope, such as more extensive documentation, may require an additional fee.
Who manages this SQL Server migration engagement?
The listed service manager for this engagement is Mike Mackey. He is identified in the service details for SKU ITPWW310MIGOT.
What happens during the migration engagement?
The engagement includes a kickoff meeting, a review of SQL Server and Windows Server, deployment start, deployment finalization, and verification with issue fixes if needed. The source provides milestone names only, so detailed milestone activities should be confirmed with IT Partner before the project begins.
What does IT Partner do during the replication setup?
IT Partner implements the SQL Server Snapshot Agent, Log Reader Agent, and Distribution Agent. IT Partner also prepares snapshot files containing schema and data for published tables and database objects, synchronizes jobs in the distribution database on the Distributor, and configures incremental changes to flow from the Publisher to Subscribers according to the Distribution Agent schedule.
What are the client responsibilities for this service?
The client must provide a dedicated point of contact to work with IT Partner and coordinate any outside vendor resources and schedules. The client is also responsible for configuring networking equipment such as load balancers, routers, firewalls, and switches, and for providing remote or physical access to required servers, systems, services, and facilities.
Are there any prerequisites for this SQL Server migration service?
The service description does not list explicit prerequisites beyond the stated client responsibilities and the relevance criteria that this approach is used when minimal downtime is needed and AlwaysOn on-premises is not available. Because environment requirements are not fully specified, clients should confirm SQL Server, Windows Server, Azure VM, access, and networking readiness with IT Partner during kickoff.
Does this service include Azure networking configuration?
The source assigns the client responsibility for configuring networking equipment such as load balancers, routers, firewalls, and switches. IT Partner’s stated responsibilities focus on implementing and operating the SQL Server transactional replication components for the migration.
Does this service include detailed migration documentation?
The included deliverable is a project closeout report showing final project status, evidence of meeting acceptance criteria, outstanding issues, and the final budget. More extensive documentation is specifically listed as not included and can be provided for an additional fee.
How are ongoing database changes handled before cutover?
Incremental changes at the Publisher flow to Subscribers according to the schedule of the Distribution Agent. The Distribution Agent can run continuously for minimal latency or at scheduled intervals, so the synchronization behavior depends on the schedule selected for the engagement.
What happens at the final cutover to Azure?
The service objective is to configure the Azure VM SQL Server as a subscriber, disable replication, and point users to the Azure database. The exact cutover plan and user redirection steps should be confirmed with IT Partner because the published service scope does not provide detailed cutover procedures.
Does this service guarantee zero data loss?
The stated success criterion is that SQL databases are available from Azure without data loss. No separate guarantee or SLA is stated in the source. The validation approach and acceptance evidence should be reviewed with IT Partner, and the final closeout report is used to document whether the acceptance criteria were met.
What is not included in this SQL Server migration service?
More extensive documentation is not included and can be provided for an additional fee. The service content also assigns networking equipment configuration to the client, so that work should not be assumed to be included in IT Partner’s scope.
What will we receive after the migration is completed?
You receive a project closeout report indicating the final project status. The report includes evidence of meeting acceptance criteria, any outstanding issues, and the final budget.
Can the migration plan be customized for our environment?
Yes, the service notes that the plan may vary depending on your needs. However, the published scope remains focused on SQL Server migration to an Azure VM using transactional replication, so any changes beyond that scope should be confirmed with IT Partner.
