The following errors show up when importing Microsoft Dynamics v6:
- “The import of solution Adobe Sign failed”
- "A SQL Server error occurred. Try this action again. If the problem continues, check the Microsoft Dynamics CRM Community for solutions or contact your organization's Microsoft Dynamics CRM Administrator. Finally, you can contact Microsoft Support"
The error during solution upgrade points to the SQL server error, which means there is a traffic overload in CRM’s DB connection or SQL server is in a bad state.
