Original: Server 2008 x86 with one instance (default) on SQL Server 2008 and the rest on SQL Server 2008R2.
New: Server 2008R2 x64 with all instances on SQL Server 2008R2.
Process: Closed all active connections to all databases on all instances and took SQL backups of every database. Then proceeded to take a block level backup via our CDP server of all partitions. Proceeded then to migrate the server from physical to virtual to our ESXi 5.1 host for comparison purposes. Next we deleted the arrays off the physical server, created new, installed Windows Server 2008R2, updated, installed SQL Server 2008R2 and created the new instances from scratch. We then detached all databases from the old SQL server that is running on the VM (and closed to outside connections) and transferred all .mdf and .ldf data to the new server. We then attached the databases and logfile to the instances on the new server.
Problem: I see that each database carried over the security logins, but the logins at the instance level are not present. Logging into the database (i.e. via GP Dynamics) states that the login does not exist. I don't want to zero out the passwords, nor delete and recreate the user logins. Is ther anyway to carry all login information over, preservering/transpiring the unique identifiers so that come Monday morning all users can login as usual?
