Upgrade a binlog cluster

You can upgrade a binlog cluster as needed. If the binlog instances in the binlog cluster run in single-replica mode, downstream business may encounter a delay of several minutes. If the binlog instances run in multi-replica mode, the system performs a leader switchover by default. This may cause a delay of several seconds to downstream business. Proceed with caution.
