hi,

i need a suggestion with you guys, I've a client which is currently using ax2012 , now he wants to move his customization and reports work to d365fo. Inshort he wants to upgrade his environment. Is there anyone who has done this task before ? If yes , then do suggest some specific steps, from where should i start from. what precautions & steps should i follow, rather than implementing customization on d365fo by writing a code.

Any suggestion would be helpful for me.

Regards,

Zohan

A logical starting point is the official documentation from Microsoft: Upgrade from AX 2012 to Finance and Operations.

Hi Zohan93,

You could use LCS to upgrade your code:

Sure, a lot of people have done it before. As suggested by others, please start by reading the documentation. In code upgrade, a big effort is to reimplement your overlayering customizations as extensions. Basically and standard Microsoft object that you have customized in AX2012 requires manual work when you upgrade to D365.

In addition to that, integrations are a big focus area. AIF is deprecated so your AIF integrations need to be reimplemented using different technology.

In some cases it might mean that. Often it's about moving your code to different place.

For example if you have added your own method in SalesTable table in AX2012, you need to move it in a separate extension class in D365.

Or, if you have customized a method in SalesTable, you need to move it to separate extension class and use Chain of Command to run your code before/after the standard code. If your customization was in the middle of a standard method you need to redesign your solution since you can't anymore have your code executed in the middle of standard methods - only before and after them.

Hi Nikolaos,

After removing custom code from AX2012 SalesTable for example, to a new ExtensionOf class in D365, what's the solution for removing the custom code from the standard code as these can't be modified?
