Here is the OS requirement for the Snapsync.

OS requirements:

SnapSync Job Type	QES Version	QuTS hero Version
QES to QES	QES 2.0.0 or later	N/A
QuTS hero to QUTS hero	N/A	QuTS hero 4.5.2 or later
QES to QuTS hero / QuTS hero to QES	QES 2.1.1 Build 20210303 or later	QuTS hero 4.5.2 or later

Other requirements:

The source and destination shared folder or LUN must be the same provisioning type (thick or thin).
If the source and destination NAS devices are running incompatible versions of SnapSync, then you will be prompted to update the system firmware on one or both NAS devices.
If both the source and destination NAS devices are running QES, then they must run the same version of QES to ensure data consistency.
When using real-time SnapSync, the round-trip latency between the source and destination NAS devices must be 5ms or less. Higher latency might cause local storage write delays.
