• Stop all WAAE services on the Primary WAAE Server. 

• Stop all WAAE services on the Shadow WAAE Server. 

• Stop all WAAE services on the Tie-Breaker WAAE Server (if it exists). *

• Edit the $AUTOSUER/config.$AUTOSERV file on the Primary WAAE Server and modify the RoleDesignator parameter from '1' to '2':

RoleDesignator=2 

• Edit the $AUTOSUER/config.$AUTOSERV file on the Shadow WAAE Server and modify the RoleDesignator parameter from '2' to '1': 

RoleDesignator=1 

• Start all WAAE services on the new Primary WAAE Server (old Shadow server). 

• Start all WAAE services on the new Shadow WAAE Server (old Primary server). 

• Start all WAAE services on the Tie-Breaker WAAE Server (if it exists). *
