When you schedule a full upgrade to NIOS 6.11 and later, you can set the RPC (Remote Procedure Calls) timeout settings and maximum concurrent connections immediately on any member as soon as you upgrade the Grid Master. When you disable the synchronization of a DNS zone, NIOS displays an error message if any Microsoft server that is a potential synchronization master, which is assigned to a Grid member, has not been upgraded to NIOS 6.11.0 or later versions.
The following happens if a DHCP failover configuration exists:
- Any Microsoft server configured to manage DHCP and assigned to a Grid member, which has not been upgraded, synchronizes the DHCP configuration without any failover related data.
- You cannot assign a Microsoft server that is assigned to a Grid member, which has not been upgraded, to any Microsoft failover relationship.
- NIOS manages any DHCP scope that is identified to be part of a Microsoft failover relationship but is managed by a Grid member that has not been upgraded, in Read-only mode.
