While upgrading Advanced Authentication from 9.1 SP4 to 9.1.5 CP1, is it possible to run the environment in a mixed mode, where some servers are on 9.1 SP4 and others on 9.1.5 CP1, with the schema upgraded to version 9.1.5 CP1?
Symantec Advanced Authentication 9.1 SP4 and 9.1.5 CP1
There are no major changes in the 9.1.5.1 database scripts compared to 9.1.04. Therefore, AA servers can be run in mixed mode with the upgraded database version 9.1.5.1, without any impact on server functionality.
