An application I have previously created which utilising a SQL Server 2008 database, however I now need to change this to MS Access.

I have changed the connectionstring to point the MS Access Database, however I receive errors when attempting to use the dataset as the connections have remained as SQLclient.SQLConnection.  

Is there an efficient way to update to change the datasources from SQL Server to MS Access?

SQLclient.SQLConnection is for MS SQL only, you will have to use OleDb for MS Access.

For example:
Dim dbConnection As OleDbConnection
Dim dbCommand As OleDbCommand
Dim dbDataAdapter As OleDbDataAdapter

But normally people are going from Access to SQL as going to Access is a step backwards.

True, not really my choice.   It has been requested to take this offsite, would there be a better option than using MS Access (without having the user install SQL Server), considering this will probably be running a standalone machine.

You can use SQL Server Express or MySQL, either would be better than Access. Even in the newer versions, Access is limited to about 2GB. The express version of SQL allows you 10GB.

If you never see the database getting bigger than 2GB, then you can use Access. They just have to realize it has limitations. Access is great for creating small applications with just a few users and I have built a lot of programs in it, but it isn't truly a database software like Oracle, SQL, or MySQL.
