Upgrade the current cluster version from v6.1.0 to v6.1.1
tiup cluster upgrade tidb-test v6.1.1 [–force] [–transfer-timeout=600]
[–force]: Indicates that the upgrade can be forced if the local tikv leader has not migrated to other nodes.
[–transfer-timeout=600]: Indicates the time to wait for the leader nodes in the current tikv node to migrate to other nodes. If there are many tikv leader nodes, it is recommended to increase this parameter value.
Note: TiFlash versions before 5.3 do not support online upgrades and can only be upgraded offline.
