I'm planning to migrate my current production SQL 2008 R2 DB to the latest SQL2019 version.
I will be planning to perform a backup and restore method, meaning taking backup from 2008 R2 and restore it to 2019. The steps should be rather straight forward. Problem is with the client connection to the database.
The current SQL 2008 R2 is configure as mirroring & for our new DB it will be configure as Active-Passive failover cluster. As I understand the connection string to connect to mirroring database & cluster DB is quite different.
Is there any best practice I can use to move all my production client connection to the new DB without manually remote into each of the client server and change the connection string?
