Transactional Replication: Replicate On-Premise SQL Server databases to SQL Azure databases

Transactional replication to SQL Azure Database is now available as of Oct 23, 2017, This feature will help us in replicating/migrating data from On-Premise SQL Server databases to SQL Azure databases with minimal impact and downtime

In this post we will see the following

1. Setup new publisher and configure new distributor

2. Add SQL Azure Database as Subscriber

For this demo we are using

Tools/Servers Used

On-Premise SQL Server 2017 Developer Edition

SQL Azure Database

SQL Server Management Studio 2017 v 17.3

How to Setup new publisher and configure new distributor


Step 1: Please connect to the On-Premise SQL Server on which we are planning to publish the data, Right click on Replication and click on New –> Publication



Step 2: Click next to continue


Step 3: We are going to configure the publisher to act as Distributor as well, but if you prefer to use a different server, use the 2nd option

After selecting, Please click Next to continue


Step 4: By default SQL Server will create the ReplData folder under Data folder, but if you prefer to use a different folder, Please change it

Please make sure the Process account which you are planning to use and SQL Server service account has rights to Read/Write to this folder else you Replication Snapshot job will fail to generate scripts


Step 5: Please select the database from which we need to publish data, In this demo we are using database “Demo”

After selecting the database click “Next” to proceed


Step 6:  Please select “Transactional Publication” and click “Next” to proceed


Step 7: Please select the required objects, you wish to replicate, we will use Customers table for this demo, after selecting the required objects, Please click “Next” to continue


Step 8: This is an optional step, if you want only filtered data to be replication, Please click on “Add…” add relevant filters

In this demo, we are going to replicate the entire table, so we will skip this and click “Next” to continue


Step 9: Please select the first option to create the initial snapshot and then use the 2nd option to setup the schedule in which the snapshot agent needs to run

Please click “Change…” to setup the schedule details


For this demo, we are setting it up to 24 hours/day for every 30 minutes


After configuring the schedule, Please click “Next” to proceed

Step 10: In this step we will be configuring the Snapshot and Log Reader Agent security settings

Click on “Security Settings…” to configure

If you want to use 2 different account for Snapshot agent and Log Reader agent, please unselect “Use the security settings from the Snapshot Agent” and use “Security Settings…” for Log Reader Agent


Please provide the Windows User account to run the Snapshot Agent


After providing the details, click “Ok” to close and then review the user name provided and click “Next” to continue

Step 11: By default “Create the publication” option will be selected, Please select “Generate a script file with steps to create the publication” if you prefer to run the script manually


If you selected the 2nd option, Please specify the path where you want the script to be created and click “Next” to continue


Step 12: Please provide the Publication Name and review the settings and click “Finish” to start the publisher/distributor configuration process


We can see the progress for each steps


After all steps are completed, we should see the Success message and click “Close” to continue


Step 13: To verify the created publication, Please refresh the Local Publications node under Replication and you should see the newly created Publication


We have successfully created the Publication now, you can verify the status of initial snapshot scripts creating by verifying the job status in SQL Server Agent – Job Activity Monitor

We can see the highlighted job as completed Successfully


How to setup SQL Azure Database as Subscriber

We will now see how to create a new SQL Azure Database subscriber

Step 1: Right click on the Replication –> Local Publications –> Publication Name and click on “New Subscriptions…”




Step 2: Click “Next” to continue



Step 3: Please review the selected Publisher and Publication and click “Next” to continue


Step 4: Please select “Run all agents at the Distributor” option and click “Next” to continue


Step 5: Click on “Add Subscriber


Click on “Add SQL Server Subscriber”


Please provide the SQL Azure Database server name and select SQL Server Authentication and provide the user name and password and click “Connect” to continue



Step 6: Please select the Subscription Database and click “Next” to continue


Step 7: Please click  “…” button to configure the Distribution Agent security


Please provide the windows user name to run the process account in Distributor Agent

For “Connect to the Subscriber”, Please provide the SQL Server Login account to connect


Please click “Ok” and then review the selected settings and click “Next” to continue

Step 8: Please specify the Agent Schedule and click “Next” to continue


Step 9: Please select “Initialize” and select “Immediately” for Initialize When, Please choose this accordingly if your snapshot agent job is completed or not

Click “Next” to continue


Step 10: By default “Create the subscription(s)” will be selected, if you prefer to create the subscription manually using script, Please select Generate Script option and click “Next” to continue


Please provide the script path and click “Next” to continue


Step 11: Please review the settings and click “Finish” to start the process


Once the process is complete, Please refresh the publication to see the Subscription


After the Replication Distribution job is run, Please connect to SQL Azure database to see the Table is created in SQL Azure database


In next post, we will see how to monitor the Replication, we will also make changes to local data and see the changes being replicated to SQL Azure

Hope you find this post helpful !!!
