Unless you want support for the MERGE command (v15), bidirectional replication (v16), and some behind the scenes optimizations, you're not really missing anything. Whether you go from v14 to v17 or v14 to v20, I doubt it'll make a difference in migration strategy. You've still got a fair amount of time before EOL. No need to stress or FOMO.
