Full Convert migration in 4 easy steps

SQL Server Express connection

Connection to SQL Server Express

We will choose SQL Server from the list of available source database engines. Depending on your SQL Server setup, you will need to connect using Windows or SQL Server authentication.

For SQL Express, we need to specify the server\instance name, like this: servername\SQLEXPRESS

We have Windows authentication here, so all we need to do is select our desired database from the drop-down list.


Connection to Vertica

We will select Vertica from the drop down and fill out the connection parameters.

Vertica connection

Start the conversion

All source tables are selected for conversion by default. In case you only need some tables, simply deselect the ones you don't need - or deselect all, then select just the tables you do need. Click the Copy your database button to get started.



Conversion is highly-optimized to run as fast as possible, yet provides top-notch reliability. Huge tables are converted in small chunks at a time, preserving memory and ensuring that your computer stays fast and responsive.
