Why You Need to Undeploy the SAS Web Applications

When you update the software at your site, SAS automatically performs these tasks:
  • rebuilds all SAS Web applications
  • redeploys all SAS Web applications
  • restarts your Web application servers
In order to update your software, you must undeploy any SAS Web applications on the tier where you are updating the software, and you must stop any Web application servers that run SAS Web applications.
Note: You need to undeploy the SAS Web applications only on the tier where software is being updated. If the SAS Deployment Wizard does not go into update mode, then no software updates are required, and you do not need to undeploy your SAS Web applications on that tier.
