It is not possible to copy a model from a CSE to HE and preserve the common ancestry because the implementation of common ancestry across the 2 types of encyclopedia is different.
If on the CSE you use the CSE server download command with options "-l" (download with upload) and "-t extract" it will create an apply.trn file.
After that file is binary file transferred to the HE the upload step will fail with this type of message:
ERROR condition was raised

Therefore for model transfers from CSE to HE you can only use the download with option "-l" i.e. this command syntax
download -u userid -m "model name" -l
(NOTE: No CSE client has that "download with upload" option so this has to be done from the CSE Server command line)
That process will create an update.trn file for binary transfer to the HE.
Any models copied over from the CSE will then have to be re-adopted on the HE to restore the common ancestry.
