I'd like to be able to convert between two Canadian vertical coordinate systems: CGVD28 and CGVD2013.  The staff at Natural Resources Canada have a conversion grid which is in ".byn" format (Canadian Geodetic Survey binary geoid file), but have offered to convert to another format if ArcGIS can't read/use it.  I don't have a handle on the different methods & formats supported, and which would be most appropriate.  Melita Kennedy‌, what can I tell them?  Or - is this file something ESRI already has in hand?

Well Melita thought it would be available in ArcMap 10.7 and in ArcGIS Pro 2.3

https://community.esri.com/message/762405-re-is-it-possible-to-apply-a-vertical-datum-transformation... 

There are other references in that thread, of which you have discovered.  Canada doesn't provide those tools other than for manual entry and not file base.  The Data Interoperability extension may have it built in at present, but I haven't checked.

Melita Kennedy‌ any news, re 2.3 or 10.7?

I replayed to the other thread. No, didn't make it. It's now on the list for 2.4/10.7.1.

Has this been added for ArcMap 10.8.1? I'm hoping it's there, but I can't find it.
Or Pro 2.6?

Sorry, not yet!! My team hopes to concentrate on geoid models/vertical transformation grids in the next release.
