Hi Andreas,
Thank you for the reply.
I am glad to know that you were able to perform the data migration ans you were also able to understand the causes for the intermittent issues.
However, please be informed that the "SQL Server Authentication" mode seeks the Login credentials for SQL server instance, for example "sa" user account.
Hence, it failed to authenticate with the business studio default login credentials HASP/HASP as these were application specific credentials.
It seems that you want to move from HASP Business Studio 5.12 to the latest Sentinel LDK 7.9. For this, I'll suggest you to raise it with our support team at support portal : https://supportportal.gemalto.com/csm .
Please be informed that HASP Business Studio to Sentinel LDK migration would require below pre-requisites :
1- HASP Business studio should be running and accessible.
2- Sentinel Master key connected over the machine.
Best Regards,
Parth Kaushik
