Migrating MySQL Databases to SQL Azure using SSMA–Part 3


In the previous posts, we saw how to download and install SQL Server Migration Assistant for MySQL v5.0 and configure utility database, and how to create a new migration project, add MySQL databases and SQL Server databases for conversion, analyze and prepare migration report.

In this post we will how to synchronize the MySQL schema to SQL Azure database and then migrate data

To convert the MySQL schema to SQL Azure schema, select the source database “ClassicModels” in MySQL Metadata Explorer and the right click and click on “Convert Schema”

image

Once the schema is converted, we will get the messages in output window similar to this (Messages will vary based on your database), if the message returns any error we need to fix it before migration

image

Once the schema conversion is complete, to migrate the schema, Right click on Target database in SQL Azure Metadata explorer and click on “Synchronize with Database”

image

Specify the password for the target server and click “Connect”

image

The schema migration preview window will display the list of objects being migrated, Click “Ok” to proceed

image

Migration process will be displayed in Output window, Once complete the output window will display the below message

image

Now we have successfully migrated the schema, To migrate the data, right click on Source Database and click “Migrate Data”

image

Specify the MySQL Server credentials and click “Connect”

image

Specify SQL Azure Target server credentials and click “Connect” to proceed

image

The data migrations process will prepare the data and start uploading the data to SQL Azure, the process details will be displayed in output window and the following message and below Data Migration Report will be displayed once the data migration completes successfully.

image

image

You can save the Data Migration report as CSV file for your reference.

You can connect to SQL Azure server using Project Houston or SQL Server Management Studio and query the data

image

Now we have successfully migrated the database schema and data from MySQL database to SQL Azure

Hope you all find this information useful !!!

Migrating MySQL Databases to SQL Azure using SSMA–Part 2


In the last post, we saw how to download and install SQL Server Migration Assistant for MySQL v5.0 and configure utility database, In this post we will see how to create a new migration project, add MySQL databases and SQL Server databases for conversion, analyze and prepare migration report.

Start the SSMA for MySQL (32 bit) by clicking on Start Menu –> All Programs –> Microsoft SQL Server Migration Assistant for MySQL 5.0

image

Create a New Project from File Menu

image

Specify the Name of Migration project, select the location where you want to save the migration project and Target to SQL Azure (Other supported targets are SQL Server 2005, 2008 / 2008 R2, “Denali”)

image

Click on “Connect to MySQL” to connect to Source MySQL Server

image

Specify the Server name, User name and Password, If required change the other parameters based on your MySQL Configuration and click “Connect”

image

Once Connected, MySQL Metadata Explorer will be populated with the list of MySQL Databases and UDFs available

image

For today’ demo, we will migrate “ClassisModels” database, you can expand the objects node to view the list of objects available in the database, You can select the list of object you want to migrate

image

Now click on “Connect to SQL Azure” on tool bar to connect to destination SQL Azure server and the specify the server name, user name and password and click “Browse”

image

Click “Yes” to proceed, The context menu will display the list of databases available and an option to create new database

image

Let us create New Database named “ClassicModels_DB” by clicking on “Create New Database”

image

Specify the name of the database and then select Database size and click “Create” to create the new database

image

Once the database is created, you will be able to see the above message, Click “Ok” to proceed. The new database name will be populated in database combo automatically

Click “Connect” to proceed

image

Once connected, SQL Azure database will be loaded in SQL Azure Metadata Explorer

image

Schema Mapping

Now let us modify the target schema, By default the Target schema will be set as Source database name, we can change it to our existing schema ex. dbo

image

Select the source schema and click “Modify”
image

Click on “…” button to browse and select the existing Schema, once selected, click “Select” to proceed

image

and then click “Ok” update the target the schema for selected source schema

image

Now we have successfully mapped the schema, let us map the types

Type Mapping

Type mapping window display the source type and destination type , if you want to change to change an existing mapping you can select a type and click “Edit”

image

Select the new Target Type and specify the length if required and click “Ok” to proceed

image

You can also add a new type mapping by clicking on “Add”

image

Character Set Mapping

In Character Set mapping window, you can view and review the character set mapped between Source and Destination database, you  can make changes by selecting the Target Charset Type combo and then click “Apply”

image

SQL Modes

In SQL Modes window, you can select what effective SQL Modes will be used during migration

image

You can make the preferred changes and click “Apply”

Now we have successfully created a new MySQL migration project, connected source and destination databases and configured the migration properties.

Let us now Analyze the migration and see the reports

Right click on the Source database name “Classicmodels” and click on “Create Report”

image

Once the report is created, it will be displayed automatically

image

If there is any errors in analysis, the object will be marked in Red, and also the messages will be displayed in bottom pane.

Based on the error message, we can fix the issue and then migrate.

In the next post, we will how to synchronize the MySQL schema to SQL Azure database and then migrate data.

Migrating MySQL Databases to SQL Azure using SSMA–Part 1


Microsoft SQL Server Migration Assistant (SSMA) for MySQL is a tool to automate migration from MySQL database to SQL Server or SQL Azure.

SSMA for MySQL v 5.0 is freely available from Microsoft, you can download it from the following link http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ac017a90-3b53-49b6-92a7-0f91623ef530

It also has free support. SSMA automates the migration process by doing schema analysis, preparing migration report and migrating data.

SSMA for MySQL v 5.0 supports migration from MySQL 4.1 and higher to SQL Server 2005 / 2008 / 2008 R2 and SQL Azure

To install and run this we need MySQL ODBC Connection v 5.1, which you can download from the following link http://www.mysql.com/downloads/connector/odbc/

Let us see how to install the SSMA for MySQL v 5.0

Once downloaded the setup from the above URL, extract the zip file and run “SSMA for MySQL 5.0

image

Select “Setup Type” and click Next to Proceed

image

image

Click “Install” to confirm and proceed with installation

image

image

Click “Finish” to complete the installation

Now we have successfully installed SSMA for MySQL v5.0.

In addition to this, we need to install SSMA for MySQL Extension Pack as well

Run the “SSMA for MySQL 5.0 Extension Pack.exe” and click “Next” to proceed

image

Accept the license agreement and Click “Next” to proceed

image

Select Setup type and click “Next” to proceed

image

image

Click “Install” to confirm and proceed with installation

image

image

Click “Next” to complete the installtion, and to start the configuration process of Utility database

image

Select the SQL Server instance on which you want to install the Utility database and click “Next” to proceed

image

Specify Authentication information and click “Next” to proceed

image

Provide a strong password to protect the authentication information stored in Utility database and click “Next” to proceed

image

Select “Install Utilities…” option and click “Next” to finish the installation

image

Once installed the following message will be displayed

image

If you want to install Utility database in another server, click “Yes” or click “No” to finish the installation

image

Click “Exit” to complete the installation.

Now we have successfully installed and configured the SSMA extension pack for MySQL.

In the next post we will see how to create a new migration project, analyze the MySQL database schema, prepare migration report and migrate data.
