I just got an issue when running the DataUpgrade package to 8.1 form the command prompt in a Cloud hosted environment. The package failed on Step 6 with this error:
Application configuration sync failed. Microsoft.Dynamics.AX.Framework.Database.TableSyncException: Custom action sync failed with error: ‘InfoException:Stack trace: Call to TTSCOMMIT without first calling TTSBEGIN.
… followed by a huge stack trace… and since I am not fluent in stack trace I did what everyone does… I call a friend
Fortunately I have great colleagues and I got the instant tip to restart IIS on the server; so I did and I reran the runbook :
AXUpdateInstaller.exe execute -runbookid=[yourrunbookid] -rerunstep=6
Presto… it worked…
