Step 3: Redirecting users to the new install

Use whatever features your servlet container provides to redirect users to the new Web Manager.

In Tomcat:

Stop the Tomcat service.

Rename swm to swm_old.

Rename swmA to swm.

Restart Tomcat.

Users now reach the new installation of Web Manager. If necessary, consult your servlet container's documentation.

The benefit of this technique is that now the 'old' version is still available and running if for some reason you must switch back to it.
