Hi Robert, before developing the documentation on Embedded Python, we discussed the ways we expected that developers would be likely use this feature. Direct access to globals was considered lower priority. Undoubtedly there are people who will have the need to do so, and we will be supplementing the documentation with additional material in the future. In the meantime, your post will be valuable for others who share your interest, so thank you for your contribution.
The quickest way to get a summary of the methods that can be used to access globals from Embedded Python is to type help(iris) from the Embedded Python shell.
If you want to move to a new server, migrating your security settings from one version of InterSystems IRIS to another is not recommended. For example, if you import your users from 2019.1 to 2021.1, you may see the following error:
ERROR #1458: Incompatible import version for Security.Users. Must be from version 2021.1.0 or later
You might want to consider doing a migration from 2019.1 to another server on the same version and then doing an upgrade to 2021.1.
If you want to stay on the same server, follow Eduard's advice.
Hope this helps!
