QuTS hero h5.1.x, h5.2.x, h5.3
Scenario
You want to know whether Snapshot Replica jobs work between NAS devices running different versions of QuTS hero, specifically when upgrading one or more devices to h5.3.
Limitations
- h5.2.x/h5.1.x → h5.3 (source to destination): Supported. Snapshot Replica jobs can send snapshots from an older version (h5.1.x or h5.2.x) to a NAS running h5.3.
- h5.3 → h5.2.x/h5.1.x (source to destination): Not supported. You cannot replicate snapshots from a NAS running h5.3 to a NAS running h5.2.x or h5.1.x.
Note: After upgrading a NAS to h5.3, it will not be able to replicate snapshots to another NAS running h5.2.x or h5.1.x. The older systems cannot accept Snapshot Replica jobs from h5.3.
Local snapshots compatibility
- Existing local snapshots remain usable after upgrading from h5.1.x or h5.2.x to h5.3.
- Snapshots created in h5.3 can still be restored after downgrading to h5.2.x.
- Local snapshots are bidirectionally compatible between h5.1.x, h5.2.x, and h5.3.
Recommendations
- Before upgrading to h5.3, review your current Snapshot Replica jobs:
- In Storage Manager, navigate to Snapshots > Replica Jobs.
- Check if any jobs replicate from a NAS using h5.3 to a NAS with an earlier version. If so, plan to reconfigure these jobs after upgrading.
- For best compatibility, upgrade both the source NAS and the destination NAS to h5.3 before configuring new Snapshot Replica jobs.
- Before upgrading, always perform a full data backup to prevent possible data loss due to unrelated issues.
- If you must downgrade from h5.3 to h5.2.x, snapshots created in h5.3 remain restorable in h5.2.x.

QuTS hero h5.1.x, h5.2.x, h5.3
场景
您想了解在升级一个或多个设备到 h5.3 时，运行不同版本 QuTS hero 的 NAS 设备之间的快照复制作业是否有效。
限制
- h5.2.x/h5.1.x → h5.3（源到目标）：支持。快照复制作业可以从旧版本（h5.1.x 或 h5.2.x）发送快照到运行 h5.3 的 NAS。
- h5.3 → h5.2.x/h5.1.x（源到目标）： 不支持。您无法将快照从运行 h5.3 的 NAS 复制到运行 h5.2.x 或 h5.1.x 的 NAS。
注意：将 NAS 升级到 h5.3 后，它将无法将快照复制到运行 h5.2.x 或 h5.1.x 的其他 NAS。旧系统无法接受来自 h5.3 的快照复制作业。
本地快照兼容性
- 从 h5.1.x 或 h5.2.x 升级到 h5.3 后，现有的本地快照仍然可用。
- 在 h5.3 中创建的快照在降级到 h5.2.x 后仍然可以恢复。
- 本地快照在 h5.1.x、h5.2.x 和 h5.3 之间具有双向兼容性。
建议
- 在升级到 h5.3 之前，检查您当前的快照复制作业：
- 在存储管理器中，导航到快照 > 复制作业。
- 检查是否有任何作业从使用 h5.3 的 NAS 复制到较早版本的 NAS。如果有，请计划在升级后重新配置这些作业。
- 为了更好的兼容性，在配置新的快照复制作业之前，建议将源 NAS 和目标 NAS 都升级到 h5.3。
- 在升级之前，请始终执行完整的数据备份，以防止因无关问题导致的数据丢失。
- 如果必须从 h5.3 降级到 h5.2.x，在 h5.3 中创建的快照在 h5.2.x 中仍然可以恢复。
