Actian Corporation recommends that you use client requesters that are the same version as the database engine. If you choose, you may use a client requester that is an older version than the database engine with which it interacts. In some situations, depending on the type of SDK access method used by your application, an older version requester will not work with the database engine. Your application will be unable to communicate with the database engine. For those situations, you must use client requesters that are the same version as the database engine.

Client requesters that are a newer version than the database engine may or may not function correctly. Actian Corporation does not guarantee that newer versions of client requesters will function correctly with older versions of the engine. Therefore, Actian Corporation recommends that you avoid the use of newer version client requesters with an older engine.
