How to convert SQL Server Express to Interbase

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.

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

Target database is known as Borland Interbase, Embarcadero Interbase (related files: ib, gdb).

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 Interbase compared to the source 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 integer
  • binary blob sub_type 0
  • bit boolean (if version at least 7)
  • bit smallint (if version earlier than 7)
  • datetime timestamp
  • datetime2 timestamp
  • datetimeoffset timestamp
  • double double precision
  • float double precision (if precision > 24)
  • geography blob sub_type 1
  • geometry blob sub_type 1
  • hierarchyid varchar(255)
  • image blob sub_type 0
  • int integer
  • money decimal(18,4)
  • nchar char
  • ntext blob sub_type 1
  • nvarchar varchar
  • nvarchar(max) blob sub_type 1
  • smalldatetime timestamp
  • smallmoney decimal(18,4)
  • text blob sub_type 1
  • timestamp blob sub_type 0
  • tinyint smallint
  • uniqueidentifier char(38)
  • varbinary varchar
  • varbinary(max) blob sub_type 0
  • varchar(max) blob sub_type 1
  • xml blob sub_type 1

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 Interbase

We will choose Interbase from the list of available database formats.

In the server field we need to type the name or IP address of the Interbase server. If you have Interbase installed on the local machine, where Full Convert is running, you can leave the server field blank. Username and password we don't need to touch in most cases as Full Convert pre-fills the "magic" values which open all Interbase databases.

If Interbase is on this machine, we can now simply click ellipsis (...) button to select GDB or IB database file (file extension depends on the version of Interbase). If the file is on remote machine, you need to type the path to the file as remote server sees it. So, if the file is in C:\t\ folder on your server, you need to write the full path, for example: C:\t\filename.GDB.

Interbase 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.
