For my “Upgrade Dynamics AX 2012 to Dynamics 365 for Finance and Operations (Preview)” project on LCS, what is the relationship between the CodeUpgrade_ExcelReport(ExcelAnalysisReport) produced from the LCS Upgrade Analysis tile and the Upgrade analyzer report from the LCS System Diagnostic tile. Are both required prior to the running Code Upgrade tool? Also, is there detailed documentation on either of the reports?
