Credit Hound versions up to and including v4.82 allow users to configure the back-end database in one of two formats, MS Access (mdb) or SQL server. 

MS Access databases were recommended for clients with fewer than 1000 accounts or 10,000 transactions. However, as your customers grow, these users may need to move to an SQL server solution. 

In Credit Hound v5 and later, the MS Access database back-end is no longer supported at all and all Credit Hound company databases must be migrated to an SQL server before the installation of v5 can be completed.

To assist with this migration, Draycir provide a migration wizard, which is copied to the Program Files folder whenever Credit Hound is installed:

"C:\Program Files (x86)\Draycir\Credit Hound\SQL Server Migration Wizard.exe"

This utility will migrate any MS Access company database to a SQL server running on 32-bit operating systems.

If your SQL server instance is on a 64-bit operating system, this migration tool will fail because of an incompatibility with the MS JET4.0 tools used to manipulate MS Access mdb files.

To migrate the data on a 64-bit operating system, Draycir have released Credit Hound v4.9 which includes 64-bit compatible tools to manipulate a .mdb database.

Operating System Architecture
Credit Hound version using MS Access back-end
Migration Process
Windows 32-bit
up to and including v4.82
Run the SQL Server Migration Wizard from the Program Files folder
Windows 64-bit
up to and including v4.82
Install Credit Hound v4.90, run the Migration Wizard from the Program Files (x86) folder, then immediately upgrade to Credit Hound v5

Establish the bitness of your SQL server

Open SQL Server Management Studio and run the following SQL query  


SELECT @@Version

You will see either x86 for 32-bit, or x64 for 64-bit in the version string

If you have a 32-bit SQL server

Run the Migration wizard for all the companies you need to migrate and then upgrade the Credit Hound application to v5

If you have a 64-bit SQL server

The Migration Wizard for Credit Hound v4.90 uses the MS Access 2010 Redistributable (MS.ACE.OLEDB), instead of MS.JET40.
