Hello,
I have moving Skype for Business Database SQL 2014 to 2019.
I backed up all databases and created instance as same name on SQL 2019 and restored databases.
But I receive error message like below.
Error encountered pushing data to RtcXds Blob Store

Hello JimmyYang,
Thank you for your answer. Actualy I see on my everythink is looking good.
The name of the computer hosting SQL Server is incorrect. / thats correct
The instance doesn't resolve the correct IP. / instance resolve right ip
The TCP port number isn't specified correctly. / port is same.
Unfortunalty skype not connect to database.
Could you verify me my steps is right or am I run some powershell script for rebuild database or another.
How did you migrate SQL 2014 to 2019 in SFB Server? Could you share the steps to us?
