Compatibility
You may have existing Micro Focus/Serena mainframe products that use an earlier version of SER10TY (2.4.4 and lower). There is no problem running products using different versions of SER10TY. The products using version 2.4.4 and lower will continue to validate licenses using the SERVERAO module; whereas the products using SER10TY 3.1 and later will validate licenses using the new process described in this chapter.
