I've tried both the recommended ways of preparing my target (production) environment: (1) switch target to enhanced data model, and (2) make a dummy site with same template then delete the website record, etc. I'm using Power Platform CLI to do the migration, since the site was built under the standard data model. Everything else the site touches has been migrated using a solution.
In both cases, CLI loads the manifest, but then the upload encounters a slew of errors, all of the type "XRM network error...entity adx_<name>...was not found in the MetadataCache". It still claims to have "created record(s) for table: adx_<name>.
But nothing shows up in the target environment as an Inactive Site.
Suggestions? thx
