After upgrading SQL Server 2014 to SQL Server 2016 (both Enterprise editions), I can't start mirror.
This works normally on SQL Server 2014.
After I restore (WITH NORECOVERY)
mirror database with full and log backups of primary database I normally run configure setup
.
After click on Start mirror
I get this error:
Database 'DatabaseName' cannot be open. It is in the middle of a restore. (Microsoft SQL Server, Error:927)
Issue with SQL 2016 GUI. Its worked with TSQL commands.
USE MASTER; GO ALTER DATABASE SET PARTNER = 'TCP://PrincipalServer:5022' GO
USE MASTER;
ALTER DATABASE SET PARTNER = 'TCP://MirrorServer:5022' GO
before executing these commands, you should have Full and log backup restore on DR with no recovery.
