With Slava's help, I was able to get this working, as follows:
We need several many-to-many relations between newly imported and original table so that we have "or" matching conditions for the various fields that might have changed.
After the two tables are matched, we will need to:
1. Export all non-matched records from the new table
2. Import the exported records into the old table: new additions (will acquire a new key field value) and existing changed records (which will be matched at import with an existing key field value).
