Magento – causing “Mismatch of entities in the document” when running migrate:delta

I have successfully upgraded a Magento 1.4.1 database to 1.4.2 and then to 1.6.0. I also successfully was able to migrate:setting and migrate:data from the 1.6.0 database over to my Magento 2.1.2 database. (Things were looking great!…)

I have since then been working on the 2.1.2 site; adding a new theme, changed some settings, and edited cms blocks. I did all this with the assumption that i could run a migrate:delta and bring over new customer and order data, as that is all i would really need to launch the new site. (I have not created any new orders or customers in the 2.1.2 database)

In my attempt to migrate:delta (after i run through the 1.4.1 -> 1.6.0 upgrade process again to get current live data) i ran into an error of missing the deltalog tables (with prefix m2cl*). I pulled those tables, which were all empty, from the first database that i migrated from. This allowed me to run a migrate:delta with the following warnings:

I guess my question is a few questions:

• Is the approach I took a correct way to get data from 1.4.1 to 2.1.2
• Is there a missing reference that the migrate:delta is looking for
  since this updated database wasn't the original one I migrated from?
• and the title question.
