MSCRM 2015 is just release in the previous last week. Maybe you come to the problem regarding the following error message:
System.Exception: Error.ActionFailed Microsoft.Crm.Tools.Admin.UpgradeDatabaseAction —> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.IO.FileNotFoundException: Could not find file ‘C:\Program Files\Microsoft Dynamics CRM\LangPacks\xxxx\sql\7\StoredProcedures\MSCRM\fn_RollupByAccount.sql
xxxx represents the MSCRM language code as 1031 for German. Here come the solution to proceed the organization upgrade from 2013 to 2015:
The following 3 files are missing for the upgrade to be completed:
The 3 files are actually allready in the filestructure, they are just named in a wrong way.
Please copy those 3 files and rename them. After all the upgrade will proceed as expected. Please note, this is an unsupported workaround. We hope of course, that Microsoft will deliver an appropiated fix for this issue.
