Applying a fix pack or an interim fix to a minimum high availability cluster
Applying a fix pack or an interim fix to a minimum high availability cluster includes the disabling of one node while the other node is still running.
During an upgrade, you must be careful about keeping the other node running to prevent an outage of B2B Advanced Communications.
Attention: The upgrade documentation may be subject to
change. Please refer to the documentation that accompanied the interim
fix or the fix pack for the latest upgrade procedure.
