Groups and accounts functionality can also be used for pass renewals. Configure a group as you normally would by setting up an account and item tree group. You can skip the account charging and password setup if this group is only used as a pass renewal group. Add the old pass DCI to the AllowedRenewals key in site config as you would normally do for a renewal (see Settings for pass renewals in detail). Edit the DCI2DCI.xml file (located in the XMLFiles directory within the E-Commerce directory) and add a record with the old pass DCI but leave the new DCI fields blank. Add the Group and Account nickname you just set up to the Group field. When a pass number corresponding to an old allowed DCI is entered in the RenewPass.aspx page that falls within the RenewalSpan, the user is redirected to the group of items just set up. When a pass is chosen the guest from the old pass is automatically attached to that pass. When the new pass is added to the cart, the user is automatically logged out of the group, so clicking on the Shop link returns the user to the main item tree for the web site.
