AX 2012 R3 CU13 upgrade

Hello folks,

I have to upgrade my AX 2012 R3 from CU 11 to CU13. In our system,

I have a few questions to discuss here.

We have 2 different ISV installed by a different vendor for a different business.

  • How to apply this CU13 changes to ISV layer models. Do I need to get this from each ISV suppliers?
  • If I get the ISV’s CU13 Model file at which point I have to install this ISV’s CU13 Model file is it before installing the Binary, application hotfixes or after completing the Software update
  • in my test server, Once I installed both Binary and Application Hotfixes and completed the whole software update checklist. the system has been tested fully and everything is fine. To apply this on all AX Production Server do I need to Install only Binary hotfixes and restore the Test Model store only. Is it correct?
