migrating context in 8.0.5 to Intermedia in 8.1.7

Hi,
I have an 8.0.5 database with Context Cartrige installed. Some applications are also written to make use of the Context Option.

Now we are upgrading our databases to 8.1.7 . How do I go about migrating the 8.0.5 database and what should be done with the applications. Does the code have to be changed or what.

Please Suggest

Ronnie
