I heard that Database Mirroring is going away in SQL Server and Availability groups will be used instead.

My only issue with that is right now Traditional Mirroring doesn't require a cluster. Clusters require domain controller permissions for the Machine accounts($machinename) to create cluster name objects in AD.

If you don't have any control over your domain, and the DC is centrally managed with a huge bureaucratic process to get things done by less-than-qualified Domain Admins, then if we want to use Mirroring for HA, we HAVE to be dependent, on a project basis, with another group to implement clustering as part of Availability Groups.

I would hate to see mirroring go away for this reason.

Can anyone confirm that Database Mirroring is going away, say in 2014 version.....or whatever.

No, it's not going away after 2012. That's wrong. It's on the deprecation list. The current plans are that once something goes on the deprecation list it should only last two versions. For mirroring that would mean 2012, 2014, vNext and gone. But I'm not sure that Microsoft is enforcing that.

I wanted to get this post up quick to refute some bad information. I'm spinning up my 2014 virtual server and I'll check on mirroring for you there to get an absolute read on it.

Yep, validated. Mirroring is still there in 2014.

You can see a listing of the deprecated features here. There are some that will be immediately removed in 2014 and there are others that will be removed "in a future version of SQL Server." Mirroring is safe through at least 2014.

Grant,

Thank you for going through the steps to let me know. I just posted a question to the SQL Team. Here is the post.


Let see what they say too. Thank you again for the due diligence.

Regards,
Alan.
