Red Item State Transitions
Objects such as hosting orders, members, contacts, invoices are simple since they do not require any action to take place on a node. They only exist in the database. Most of these objects have just two states: active or deleted.
Red items, however, are different since a state change is first recorded as pending in the database. Then, asynchronously, the node attempts to implement the change state and reports a new state based on the outcome. Below is a description of the state changes. Most are self-explanatory.
transfer-limbo is a state specifically used when a hosting order is being copied from one node to a different node. Normally, two items with the same unique identifiers cannot co-exist on two different servers. transfer-limbo is an exception - in which to items can co-exist if one of them is set to the transfer-limbo state (items in this state cannot be modified - they can only be deleted once the transfer is complete).
