I am upgrading our Development environment from AX 2012 CU3 to R2. During the upgrade, I am stuck at the Presynchronize step in the Data Upgrade checklist. I have a clean compile, a CIL generation, and clean synchronize. The Presynchronize step finished fine and if I click on it again it displays a form showing all the steps finished. I haven't been able to find any way to get past this step to finish the Data upgrade checklist.
Any ideas are appreciated.
