I now face a fundamental challenge when trying to generate a migration while my model has already undergone significant modifications and my database is out of sync (up to the most recent migration, I have no database at all).
The specifics are as follows:
I understand that I can now execute #4 following the failure in #5. Then try #5 again, and success.

Apply migrations first, then specify the final one.
PM> Update-Database -TargetMigration AnyMigrationName # It updates database to a migration named "AnyMigrationName" # This will apply migrations if the target hasn't been applied or roll back migrations # if it has
You merely add a new migration when your local database is updated.
PM> Add-Migration NewMigrationName # it scaffolds a new migration named "NewMigrationName"
In search of a reliable reference These blog postings on Migrations EF that I found may be of great assistance to you. They cover a wide range of topics, but particularly Zzz-29 Zzz and Zzz-33 Zzz.
When you have numerous pending migrations, this error is displayed.
If you don't need existing migrations, first delete (exclude) all migration on Migration folder and then add a new migration.
