Guess what, more companies are moving to NAV 2013 R2.
I am about to start a data upgrade for a medium-sized Icelandic company. Doing a data transfer means that you need to compare the tables of the old version and the new version and where you have mismatch you have to take some action. The data transfer is build on the upgrade from 2009 to 2013 R2 released by Microsoft.
This video demonstrates how to use the Transfer Customs Fields Pattern in Microsoft Dynamics NAV 2013 R2.
In November 2010 I blogged about Transferring small amount of data between databases. There I had a Form that can read and write a XML file with table data. This Form was used frequently in my company to move data between companies and databases.
The good thing about this method is that I can move data between database versions.
Transfer orders are also a source of supply when working at the SKU level. When using multiple locations (warehouses), the SKU replenishment system can be set to Transfer, implying that the location is replenished by transferring goods from another location.
