Abstract
A migration system for distributed control system migration uses a parser that parses system configuration information for a source control system into an intermediate language. A block equivalence module then finds destination system control blocks that are equivalent to source system control blocks and builds logical control loops using the destination system control blocks. In one embodiment, some source system control block may be migrated to two destination system control blocks. Selected source system control blocks may have integrated alarms. Such control blocks may be migrated to control blocks with separate alarms blocks.
