• Mirroring is deprecated as most/all of it's features are superceded by AlwaysOn Availability Groups in SQL 2012+

    It's still present in SQL 2012 & 2014. Haven't done it myself but should be a reasonably easy conversion if you ever need to.

    It's worth noting Mirroring has a nifty feature called Automatic Page Repair, which fixes certain types of corruption by recovering the intact version of the corrupt page(s) from the mirror. http://msdn.microsoft.com/en-us/library/bb677167(v=sql.105).aspx

    Edit: for mirroring you'd need the ability to update any app's connection strings to include the FailoverPartner option. Might not be an option if it's a third party app.
