The instance name is optional and defaults to the default SQL Server instance in the source host. Now put your credentials user name and password to connect to the server. If you know the name of the database you want to migrate, put it in the Database field. Otherwise leave it blank and you will be later given a list to select your database there. At this point you should have something like this:. If you put the right parameters you should see a message reporting a successful connection attempt.
Click on the Next button to move to the Target Selection page. When you are done click on the Test Connection button and verify that you can successfully connect to it. Click on the Next button to move to the next page. If you left blank the Database field in the Source Selection page it will retrieve all of the catalogs in the server. Otherwise it will just fetch the schemata corresponding to the catalog you explicitly typed.
Verify that all tasks finished successfully and click on the Next button to move forward. You will be given a list of catalogs and their corresponding schemata to select the ones to migrate. Keep in mind that you can only migrate schemata from one catalog at a time.
The Schema Selection page will look like this:. Select the Northwind sample database from the list and its default schema dbo. Now look at the options below. A SQL Server database is comprised of one catalog and one or more schemata. MySQL only supports one schema in each database to be more precise, a MySQL database is a schema so we have to tell the Migration Wizard how to handle the migration of schemata in our source database.
We can either keep all of the schemata as they are the Migration Wizard will create one database per schema , or merge them into a single MySQL database.
The two last options are for specifying how the merge should be done: either remove the schema names the Migration Wizard will handle the possible name colisions thay may appear along the way or either adding the schema name to the database object names as a prefix.
Move to the next page using the Next button. You should see the reverse engineering of the selected schema in progress. At this point the Migration Wizard is retrieving relevant information about the involved database objects table names, table columns, primary and foreign keys, indices, triggers, views, etc.
You will be presented a page showing the progress as shown in the image below. It may take some time, depending on how fast is your connection to the server, your SQL Server load and your local machine load. You can also open the report in Excel to get an inventory of MySQL objects and the effort required to perform schema conversions.
Validate the default data type mappings and change them based on requirements, if necessary. To do so:. It doesn't load the information into the instance of SQL Server. Use the output and error information to determine whether you have to modify your MySQL databases or your conversion process to obtain the desired conversion results.
Optional To convert dynamic or ad-hoc queries, right-click the node and select Add Statement. Alternatively, you can select the Convert Schema tab in upper-right corner. After the conversion finishes, compare and review the converted objects to the original objects to identify potential problems and address them based on the recommendations. In the output pane, select Review results and review the errors in the Error List pane.
Save the project locally for an offline schema remediation exercise. On the File menu, select Save Project. This step gives you an opportunity to evaluate the source and target schemas offline and perform remediation before you publish the schema to SQL Server.
After you have the necessary prerequisites in place and have completed the tasks associated with the pre-migration stage, you're ready to perform the schema and data migration. Installation and Configuration: MySQL usually takes 15 minutes or less for downloading and installation. Flexibility: SQL Server uses a single storage engine.
However, MySQL provides developers great flexibility to choose different storage engines for different table types. Step 1: Database Schema Conversion The schema is a visual representation of how database is structured. This procedure does not support conversion of indexes, foreign keys, identity columns, unique or other table constraints, and character set.
Moving large volumes of data involves risk of data loss. It can be an overwhelming and challenging task for novices. I need two things, A good migration tool, and something similar to management studio to manage it. Save my name, email, and website in this browser for the next time I comment.
