If one of the features lz4_compress, zstd_compress or large_blocks is actively used/required by the source dataset, but not enabled on the destination, zfs send/recv will fail and recommend upgrading the pool.
It's not required that the target dataset is also compressed. Specifying '--properties' to have the target inherit the compression property even works during later syncs (but pre-existing data won't be recompressed automatically then).
