We may still need to keep the old validation task that uses the /smi/raw catalog while the data is still being written to Mongo (and add the new validation of the /smi/migration catalog). It doesn't cost us much (correctly me if I'm wrong), but for completeness I think it makes sense to keep it.
We can the old function once Mongo is turned off and /migration is renamed /raw.

so you want to keep the task that reads all data as a check for /smi/raw? we should talk about this more - this change would remove one of the major advantages of this PR, that we are not reading all of the data, which could be the main reason for prefect-worker2 CPU usage issues.

Ah okay, if improving the performance was the main reason -- maybe just remove it then. I don't know if anyone paid any attention to this reading failing.
Validating /migration (what you've added) is important though; it fixes any inconsistencies in structures to make the data readable.

logger = get_run_logger()
api_key = Secret.load("tiled-smi-api-key", _sync=True).get()
tiled_client = from_profile("nsls2", api_key=api_key)
run_client = tiled_client[beamline_acronym]["migration"][uid]
run_client_raw = tiled_client[beamline_acronym]["raw"][uid]
logger.info(f"Launching tasks to check streams and validate uid {uid}")
start_time = ttime.monotonic()
check_stream_task = check_stream.submit(run_client_raw)
validate_task = validate_local.submit(run_client)
logger.info("Waiting for tasks to complete")
check_stream_task.result()
validate_task.result()
elapsed_time = ttime.monotonic() - start_time
logger.info(f"Finished checking and validating data; total {elapsed_time = }")
