If you have a System Architect V10.3 encyclopedia that you linked to DOORS, you will need to update that encyclopedia with SAEM to reestablish the link.
1 Backup the encyclopedia. You can do this using SAEM (run SAEM, connect to your server, choose the encyclopedia, and select Database, Backup).
2 Launch SAEM.
3 Click Tools menu, and select Update DOORS. The message pane at the bottom of the SAEM window confirms your results.
4 Open the encyclopedia with System Architect V10.4. The links should now be updated to work with System Architect V10.4
