Hi Benjamin,
The transition from MDA to AA is a manual process to move from MDA to AA, it is described in the KB article #897742. It explains that you will need to manually set up all MDA groups and codes in Analytical Accounting.
Regarding your historical MDA data, you can enter a beginning balance for your dimension codes in AA. The following KB article describes how to enter those beginning balances for AA dimension codes:928924 How to enter beginning balances for your dimension codes in Analytical Accounting in Microsoft Dynamics GP
