How to handle SSIS Validation error 16253?

I'm new to SSIS 2005 (I usually load via T-SQL).  I've added a dimension table to the database that has an identity colulmn that is used to create the Key number rather than use the source's ID column.  

In SSIS, I added a Data Flow task that is used to load the data from a view of the source table (created using a linked server).  I have a Slowly Changing Dimension data flow item so that the process doesn't add another set of records each time.  I just want to add the new ones and update the edited ones and I was told this was the way to do it.  It this is not the way to do it, let me know.  

The issue:
I now have an error on this task that reads:

Error      5      Validation error. dimActivity: Slowly Changing Dimension [16253]: The "input column "ActivityDesc" (16956)" has a long object data type of DT_TEXT, DT_NTEXT, or DT_IMAGE, which is not supported.

ActivityDesc in the source is ntext which, obviously, isn't supported in the Slowly Changing Dimension.  

What is the recommended way to handle this situation?

Thanks!

change ActivityDesc to DT_WSTR datatype
you can do this with :
data conversion transformation
or
with advanced editor of source and changing the output column type in input/output columns tab.

A little bit off-topic: using a SCD technique is the way to go, but using the standard SCD component from SSIS isn't. It is notoriously slow for updates, as it issues a single UPDATE statement for each row. It is better to implement the SCD yourself in SSIS using T-SQL, or to use the Kimball SCD from Codeplex.

Regarding your actual problem: convert it to DT_WSTR, as reza_rad suggested. In the destination database you have to create a (N)VARCHAR(MAX) column.
