A HiRDB update version has the same version number and revision number as the active HiRDB, such as 07-02, followed by a code, -mn; for example, 07-02-/A, where the underlined part is the -mn code. For versions earlier than 07-03, m can be a /, an alphabetic character (excluding I, O, and P to T) or a number, and n is an alphabetic character from A to Z. For versions 07-03 and later, m and n are both numbers.
You can switch to the HiRDB update version while the existing version of HiRDB is running. However, if you use the system switchover facility with MSCS or MSFC installed, the switch cannot occur while HiRDB is running if HiRDB services have been registered as generic services of MSCS or MSFC.
