Convert SQL Server Express to Oracle

Full Convert is designed for ease of use and reliability to make sure you get your job done as quickly and as simply as possible.

SQL Server Express is also known as Microsoft SQL Server Express, Microsoft SQLExpress, SQL Express, SQLExpress (related files: mdf, ldf, bak).

Making migration easy for you

Full Convert is a fully self-tuning software. Your migration will work as expected without you needing to adjust anything.

Data types are different in Oracle compared to SQL Server Express. We automatically adjust them as we copy the tables so you don't have to worry about it. You can adjust the mapping rules if you wish to change the following defaults:

  • bigint number(20)
  • binary blob
  • bit number(1)
  • datetime date
  • datetime2 date
  • datetimeoffset timestamp
  • decimal number
  • double binary_double
  • float binary_float
  • geography sdo_geometry
  • geometry sdo_geometry
  • hierarchyid varchar2(255)
  • image blob
  • int number(10)
  • money number(19,4)
  • nchar nclob (if precision > 1000)
  • ntext nclob
  • nvarchar nclob (if oracle_extended is true and precision > 16383)
  • nvarchar nclob (if oracle_extended is false and precision > 2000)
  • nvarchar(max) nclob
  • smalldatetime date
  • smallint number(5)
  • smallmoney number(19,4)
  • text clob
  • time date
  • timestamp raw(8)
  • tinyint number(5)
  • uniqueidentifier raw(16)
  • varbinary blob
  • varbinary(max) blob
  • varchar clob (if oracle_extended is true and precision > 32767)
  • varchar clob (if oracle_extended is false and precision > 4000)
  • varchar(max) clob
  • xml xmltype

Full Convert migration in 4 easy steps

1.
SQL Server Express connection

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.

2.

Oracle

We will choose Oracle from the source database engines list. We can connect to our Oracle in two ways. If we have Oracle Client installed, simply typing the service name and specifying login info is all we need.

However, when you don't want to install 100MB+ of OCI installation, we have a nice surprise! We can connect to Oracle using a direct TCP/IP connection. No OCI required. In addition to database name and login info, we would just need to specify server name or IP - and done.

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.

4.

Conversion

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.
