We are planning to migrate SQL Server 2008 to SQL Server 2016 AlwaysOn.
We have to minimize the down time.
Because the DB size is 4 TB.
I am using GUI to Add DB to HA, so it will automatically take backup,restore and add to HA.
If i do in this way it take hours together to add to HA.
SO, Is there any way i can add DB to HA to minimize the Downtime.
