Orchestration activity packs The base Orchestration system includes packs of custom activities you can use to automate typical IT and business processes in your network. Activity packs allow you to automate a number of common business processes, such as managing Active Directory accounts and Exchange server mailboxes. Additionally, activity packs can automate IT functions such as starting and stopping Windows servers, joining domains, assigning IP addresses, and configuring load balancers.Note: A number of activities have been converted to use the new template format and databus offered with the activity designer. These custom activities are organized into activity packs that are easier to use than their legacy counterparts and do not require scripting. Workflows in upgraded instances that use legacy activities will continue to work normally. However, all new workflows must use activities from the activity packs.
