AX2009: Initialization checklist starting instead of upgrade checklist

Hi all,

I experience the following problem during my upgrade process from Ax 3.0:

I did not really upgrade anything yet but have installed AX 2009 without starting AOS, copied over the old files from AX 3.0 into the Appl and Old folder according to upgrade guide and upgrade training material and renamed DIS and DIP files to HFX and SL1 respectively in the “Old” folder. Now when starting AOS the first time it takes about 15-20 until it is running, which is ok. But when I start the client the initialization checklist starts instead of the upgrade checklist so I can not really start with code upgrade. Has someone made the same experience and got it solved or does anyone know who AX determines whether to start the initialization or the upgrade checklist?

Thanks in advance
