About Upgrading from DCA 1.0 
DCA 2.01 is not simply an update from DCA 1.0 -- it is a separate application based 
on a different architecture. DCA 2.01 uses different mechanisms for session creation, 
page sharing, and other core functionality. 
Due to DCA 2.01's more advanced feature set, its hardware requirements and 
performance specifications are different from those for DCA 1.0. You cannot install 
DCA 2.01 over DCA 1.0. 
If you are a DCA 1.0 user upgrading DCA 2.01, perform these steps prior to installing 
DCA 2.01: 
1. Inventory DCA 1.0 settings and customization 
There is no automated way to port settings and customization from your DCA 
1.0 server to DCA 2.01. Therefore, take an inventory of settings and 
customization you introduced to DCA 1.0, and decide which, if any, you will 
want to re-create on your DCA 2.01 server. Under no circumstances should 
DCA 2.01 properties files simply be overwritten with files from 1.0. 
Note that the following DCA 1.0 customization features have been deprecated 
in DCA 2.01. In 2.01, the behaviors available through these features can be 
achieved through parser customization. 
• 
Agent link deadening (used to disable specific link types, for example, 
SUBMIT buttons, for agents in a DCA session) 
• 
Customized Form code (used to automatically insert additional code after 
the last Form on a Web page) 
• 
Snippets (used to automatically insert additional code into a Web page's 
source code) 
• 
User patterns (used to define link parsing rules) 
2. Uninstall DCA 1.0 
DCA 2.01 cannot be installed over DCA 1.0. If you plan to install DCA 2.01 on a 
machine on which DCA 1.0 was previously installed, first uninstall DCA 1.0. To 
ensure that DCA 1.0 uninstalls cleanly, be careful to follow the uninstall 
instructions included in your DCA 1.0 documentation. 
You should also delete the DCA 1.0 alias for the DCA Admin Tool defined in 
your Web Server software.
