On previous occasions I have reviewed and . Now its time to look at yet another new product from SwisSQL called "Data migration tool". Good thing about this tool is that, it is more like a simple wizard, that takes you through the migration process in a clearly defined step by step approach. Compared to the previously reviewed tools, the user interface provided by this tool is much more appealing and is easy to use.
This is a complete Data Migration Tool sthat helps the migration and transfer of database schemas and data across leading databases such as Oracle, IBM DB2, Microsoft SQL Server, Sybase, SAP DB, and MySQL. It supports the recently released Microsoft SQL Server 2005 as well, also known as Yukon.
You can download a trial version of this software from swiss sql website. You can also get technical support during this free evaluation. For this, you just need to fill in a simple form (on the download page) with your contact information.
Now lets get straight to the review. The evaluation version is good for 30 days and will let you migrate 10 tables, 10 indexes, and 5000 rows of data per table.
Make sure you download the installation which includes the Java Runtime Environment (JRE). Though the installation with JRE is bulky (16 MB, compared to 5.5 MB of installation file without JRE), it is worth downloading, as it'll save you time configuring the required JRE settings manually.
Installation is pretty straight forward, apart from the following issues. If you are running the setup on a Windows XP SP2 machine, XP will warn you saying the publisher for this software is 'Unknown'. This product is based on Java, and requires Java Runtime Environment. But Windows XP SP2 firewalls blocks Java from running. For this product to work, you have to make sure you are not blocking Java.
Here's how the product looks like, when you first open it:
Now I will walk you through the steps of migrating tables, indexes and data from one RDBMS to another RDBMS. As you can see from the first screen shot, this tool provides a wizard based user interface. And you can clearly see on the left hand side of the window that there are 7 steps involved in the migration process. In the first screen you either have to create a new migration project or select an existing project file, and click the Next button.
This leads you to step 2, where you select your source database management system. From the 'Select source database' combo box, select your database server instance, which can be either Oracle 8i, 9i, 10g or SQL Server 7.0, 2000, 2005 or Sybase ASE 11.x, 12.x or DB2 UDB 7.x, 8.x or MySQL 3.23.x, 4.x, 5.x or MaxDB 7.5. The screenshot of this screen is shown below:
After selecting your source database management system, click Next button. This leads you to step 3. In this step lets you specify the connectivity information for your source database. Here, you will specify information like the database server name, login and password for connecting to your database server, the database name, and an optional port number. The wizard automatically picks the default port number for the specified database system. Screenshot for Step 3 is shown below:
Specify the required connectivity information for your source database system and click Next button. This leads you to step 4. In this step, you have to select your target database management system. Pick the target database management system from the 'Select target database' combo box, which provides a list of support RDBMSs. Screenshot of step 4 is shown below:
Select your target database system, and click the Next button to go to step 5, where you specify the connectivity information for your target database. Here you will provide the server name, database name, login, password, port number etc. Screenshot of step 5 is shown below:
Provide the required connectivity information and click the Next button to go to step 6.This step lets you select the tables, data and indexes from your source database connection, that you want to migrate to your target database system. Here you can specify whether you want to drop the object if it already exists on the target system. This screen also lets you specify the criteria for data to be transferred. Basically you will provide the WHERE clause for the table to specify which rows qualify for migration. In the criteria dialog box, you can press Ctrl + Space to get a list of comparison operators like >, <, = etc. Screenshots for this screen and provided below:
Select the tables, indexes and specify the required data filtering criteria in the above screen. Click the Next button to go to step 7. In this step, the wizard summarizes your selection of source and target servers and databases and the tables and data that you have chosen to migrate. Click Next button on this screen to perform the migration. In step 7, the wizard looks as shown below:
When you press the Next button on the above screen, the actual migration takes place. The last screen shows the progress of migration as it happens, along with success/failure of individual object transfers, and the total time taken by the process. This screen has a Details button. When clicked, it shows you information about your source and target servers and the objects that you've chosen to migrate. The Summary button shows you details of the transfer of individual objects. This screen is pasted below:
Now you can connect to your target database server and check to make sure all the objects are transferred correctly. I checked my target server, and all the objects that I selected, got transferred correctly.
This product is a big step forward by SwisSQL, as it simplifies the process of migration, with much better user interface, compared to its previous products. The user interface looks very much similar to the well known, SQL Server DTS data transfer wizard. Well, this is it for now. You can download a free evaluation version of AdventNet SwisSQL Data Migration Tool 3.0 from here Note that SwisSQL provides free technical support during the evaluation period.
