Replicating snapshots to different (older) TrueNAS versions (Core/BSD)

Question for the guru’s. Are you aware of limitations in replicating snapshots to different versions of TrueNAS?

I’d like to deploy a new TrueNAS 13.3 Core server, and replicate snapshots to an older FreeNAS 9.10 server, for backup purposes. Any known limitations?

I could wipe out the old FreeNAS 9.10, and install 13.3 Core, after I migrate my data, but I’m worried about lack of hardware drivers for my older equipment.

Any insights appreciated!
