recommended that the TiUP version is 1.11.0 or later. tiup update --self tiup --version 2. Upgrade the TiUP Cluster version. It is recommended that the TiUP Cluster version is 1.11.0 or later. tiup update cluster effect automatically if the following conditions are met: • TiCDC is v6.3.0 or later. • TiUP is v1.11.0 or later. • At least two TiCDC instances are running in the cluster. 2509 13.9.2.6 Modify TiCDC TiCDC supports graceful upgrade #4757 @overvenus @3AceShowHand When TiCDC is deployed using TiUP (>=v1.11.0) or TiDB Operator (>=v1.3.8), you can gracefully upgrade the TiCDC cluster.

地址，可跳过本步骤，然 后更新 TiUP 离线镜像。 1. 先升级 TiUP 版本（建议 tiup 版本不低于 1.11.0）： tiup update --self tiup --version 2. 再升级 TiUP Cluster 版本（建议 tiup cluster 版本不低于 1.11.0）： tiup update cluster tiup cluster --version 更新 TiUP 起支持滚动升级，使用 TiUP 升级 TiCDC 节点期间，能够保证同步延迟稳定，不发生剧烈波 动。满足以下条件将自动启用滚动升级： – TiCDC 版本大于等于 v6.3.0。 – TiUP 版本大于等于 v1.11.0。 – 集群中至少有两个正在运行的 TiCDC 实例。 13.9.2.6 使用 TiUP 变更 TiCDC 集群配置 本节介绍如何使用 TiUP 的tiup cluster edit-config 保持一致。借助此能力，TiCDC 能更好地匹配读写分离应用场景，帮助用户降本增效。 • TiCDC 支持平滑升级 #4757 @overvenus @3AceShowHand 用户使用TiUP (>=v1.11.0) 和 TiDB Operator (>=v1.3.8) 可以平滑滚动升级 TiCDC 集群。升级期间数据同步延时保 持在 30 秒内，提高了稳定性，让 TiCDC 能更好地支持延时敏感型业务。
