Error in BC cloud migration when defining SQL database connection

apquintas

We would like to know the reason of getting this error sometimes in the 1st steps of the BC Cloud Migration Setup (OnPrem to Cloud)

,when trying to establish connection to origin DB, after providing the SQL Connection String and the Integration Runtime Name.


It seems to be completely random and related to the failure of some cloud resources, but we don't know. We get the error for a few hours and then (or the next day) it works... or not.

This unpredictability is very dangerous specially in the case of a Production related cloud migration.

We would really appreciate if someone could give us some input to help us understand this error

SOLUTION: (at least for this time it worked)
Revoke and Grant again delegated admin consent for cloud migration.

What is the Source - GP, BC Prem?

@RockWithNAV thanks for the question. I edited my Post title and 1st line. It's related with BC Prem to Cloud

Ok. Couple of Suggestions as system is complaining on authentication's.

• Make sure we have no permission issues. AD as well as on the BC.
• Server should be exactly the same where you are running BC Prem and Cloud with the SQL.
• SQL Server Information and the way you are passing the param's has no error.

These were some when I did and it worked.
