Having the same OneFS version and patches on both the source and target cluster is recommended but is not always possible in some environments due to various factors.
Note: As a best practice, upgrade the target cluster before upgrading the source cluster to ensure that no interruptions to replication jobs occur as part of the upgrade process.
OneFS 8.2.2 introduces large file support for 16 TiB files. When enabled, a source or target cluster only establishes connections with clusters that have the 16 TiB feature enabled. For more information about the 16 TiB feature, see 16 TiB large file support and SyncIQ implications.
If the source and target cluster are running different versions of OneFS, to confirm SyncIQ compatibility see the following table.
Source Cluster OneFS Version | Target Cluster OneFS Version | ||
7.2.x | 8.x and 9.x+ | 8.2.2 and 9.x+ with 16 TiB feature | |
7.2.x | ✔ | ✔ | X |
8.x and 9.0+ | ✔ | ✔ | X |
8.2.2 and 9.0+ with 16 TiB feature | X | X | ✔ |
