Migration Mechanics/Selection
There are four migration processes. The first is the normal migration
process. Only non-emergency migration requests will be considered. The
second is the rush migration process. Only rush or emergency migration
requests will be considered. This process is done by Production Control.
The third process is the emergency migration process. It is the same as
the rush process except it is initiated by Operations. The fourth
process is the integrated TOS process, used only for SCT TOSs.
In addition, the following selection criteria are used when selecting
migration requests for processing:
- Migration Date
- A migration request will only be selected for processing if the
migration date specified has been reached. Emergency migration requests
bypass migration date checking.
- Approval Status
- A request must be marked as approved to be selected for processing.
- Previous Errors
- If a migration request was previously processed and errors were
detected, it will not be selected for processing.
