I am already aware of the differences between the 2 products (AX vs. NAV) . Has anyone migrated from AX 2012 R2 to NAV ? Just wondering what would be involved in the backend (ie: databases ,tables, customizations) to move from AX database and model store to NAV. I'm not familar with with the NAV backend other than it primarily runs on .NET architecture running atop a SQL database . Any help would be appreciated.
The process is quite straight-forward, however not so typical :-).
You would need to transfer the opening balances at some cut-off date from AX to NAV. This is relatively easy accounting process itself, you can export the open balances to Excel from AX and import them to NAV.
The difficulty here is to synchronize the chart of accounts and analytical structure, as when you transfer financial data from one system to another this is usually a challenge to map them together. You thus do no need to know much about the (SQL) table structure as such for both systems - rather to be able to operate with finance data efficiently.
Another challenge is to analyze and streamline business processes the way that users and your business itself will operate efficiently. This is usually done via fit-gap analysis where you indicate the gaps that NAV standard functionality does not support out-of-the-box, and then decide either to change the process or go for customization. Remember there is nothing in AX that you cannot develop in NAV, but you should be very careful in deciding to customize the standard to avoid unnecessary changes.
* analyse and describe the standard and custom business processes in ax
* compare with nav standard processes, check what is the gap, what is needed for customization
* compare which additional table fields are needed in nav
* export all master data and if needed transaction data, find a propriate way for import (e.g. rapid start services)
