How do I transform from NAD83-Original (1994) to NAD83-CSRS for areas which don’t have a provincial grid shift file? (e.g. Yukon, NWT).
All new incoming data are NAD83-CSRS and I want to bring our older holdings up to match. I don’t have confidence in the automatic methods chosen by ArcMap/Pro/others in project-on-the-fly situations. I’ve seen too many instances where different coordinates are reported for same points from different methods.
With csmapReprojector the process fails with:
CS-MAP Reprojector: Transformation will be automatically selected for 'UTM83-8' -> 'CSRS.UTM-8N', and is not guaranteed to remain the same in future releases of FME
CSRS :: Referenced grid file does not exist or cannot be opened for reading.
A fatal error has occurred. Check the logfile above for details

With EsriReprojector the process succeeds but log warns:
EsriReprojector: Ignoring input feature coordinate system `UTM83-8'. This warning will not be repeated.
Esri Reprojector: Specified geotransformation `' (forward) may be inappropriate for reprojection from `_UTM83-8_0' (GCS: `GCS_North_American_1983') to `_CSRS.UTM-8N_0' (GCS: `GCS_North_American_1983_CSRS') using the ESRI reprojection engine
