Refer to below articles,
The custom geographic transformation files are stored under user’s profile.
For cloud based, enterprise environment, this is quite bad to make these custom transformation files available for every single users.
We can have an addin to monitor the centralized unc location and load into the profile upon user triggers the arcpro.
However I think, it could be the best if we can make arcpro to point unc network path as centralize location to load these custom geographic transformation file.
Is that possible?
If it is possible how to do?
