Points of My Scenario:
1. I am both Windows admin and SQL Server sysadmin of two SQL Server 2016 servers.
2. Databases on Server-A are mirrored to Server-B: the servers are at different sites connected by WAN link .
3. Server-B needs to be replaced due to OS corruption that not even Microsoft can resolve.
4. The databases are too large to backup and send from Server-A to a new mirror partner server (e.g. Server-C).
5. I need the new server (Server-C) to use the mirrored database files on the problem Server-B to re-establish the mirror.
Note 1: Server-B is still running, but crashes regularly (2 - 3 times daily), and management wants it to be replaced before it stops running altogether.
Note 2: Server-C will need to be configured with the NetBIOS name of Server-B so that applications at the site will work if/when we fail-over.
QUESTION: How can I make a new server (Server-C) into a mirror partner for Server-A, using the database files from Server-B?
