AX 2012 R2 upgrade - how to move new development changes


We have upgraded from Ax 2012 R1 to Ax 2012 R2. Moved all the CUS layer changes to R2. During the upgrade we got some developments done in R1, which we are trying to deploy into AX 2012 R2 straight from R1 Test environment.

As the new developments got some new objects and new fields added to some of the standard AX tables.

How we can put the AX production database(of R1) which has not got these developments to the new upgraded AX 2012 R2.

Any suggestions

What is the best way to do this?

How the object Id’s would be effected and what are the consequences.

Kind regards.
