We currently have multiple EEM 12.51 CR04 servers configured for multiwrite / failover but don't want to upgrade the EEM servers to 12.62 all at the same time.
Is EEM mult-iwrite / failover supported if EEM versions are 12.51 CR04 and EEM 12.6?
EEM versions 12.51 CR04 and EEM 12.62 can work together in a multi-write setup. For failover to work, the EEM versions must be the same.
