QUESTION
I apologize if this is duplicative; I could find nothing directly pertaining.
The difficulty involves EF Core (v 3.1.8, if it matters), but is not specific or restricted thereto. I am doing code first, creating a number of entities, but the key point is that I am getting my initial data set from an app that I am trying to replace. My new app has a number of structural differences in every corresponding entity, but the data in the old app is still critical, so I will be transferring it to my new database. (Old db is hosted by MS SQL 2008; new db is hosted by MS SQL 2019, if it matters).
Most of the key fields are GUIDs, and the problem is that in EF Core, at the point in the future when I want to use the new app to do more data entry, I will also want the database to choose the GUID. In EF Core Fluent API parlance, that would be, for example:

Answered 2020-Oct-28 at 23:53Not being an EF programmer, I don't know if there is an option for identity insert that you can enable for a migration. You might search the term to see if it comes up.
Our team support database migrations. We can do it a number of ways. I would not even consider EF because it's not designed for data migrations - or for database design. (And because we tend to use what we know.)
This is not the way I would do it, but it might be better than SSIS if you have not used SSIS. If the tables are in the same database or in databases on the same server, you can use T-SQL to load each table one at a time. Even if not on the same server, a linked server would allow a distributed transaction. (I avoid linked servers like the plague, but for a one time thing like a migration I would tolerate it. I would rather restore a copy of the source database to the destination server to use as a source. Distributed transactions gone wrong have forced me to reboot critical servers.)
Each table can have a 4 part name. If the server part (e.g., using a linked server name) is not present, the local instance is used. If the database part is not present, the current database is used. This is the format I assume for the "src_table" and "dst_table".
[myserver\myinstance].[mydatabase].[myschema].[mytable]
Each table is loaded with T-SQL as follows:

Install unmung
You can use unmung like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
