ERP Migration completed at one of our customers

At the beginning of this month we completed an ERP migration at one of our customers. 

This customer works at different subsidiaries with different versions of the same ERP system, where they would like to see both systems merged into one system.

We have set up a 'clean' database for this and we loaded the first three subsidiaries into this new database beginning of June. We were able to immediately clean up outdated data.

The last two subsidiaries have been added in October and December to this database.
