Server 2012 Migration

Can someone give me some 1, 2, 3 steps that can assist me in finishing a server upgrade?
We had to let our IT consultant go and he was partially done with the upgrade from Server 2008 to Server 2012.     Here is what I know he finished:    This is a virtual server and 2 terminal (virtual servers)
Server and roles are established.
Active Directory is complete
GPO is complete
Virtual servers are set up and working fine---applications, RDP, etc.

I think I am just down to copying the data files????       Or can you think of steps I need to complete or check if they were done?

Also, after I copy the data files, what or how do I make sure all users are now accessing the new data server and not the old one?

IE:  our directory is \\bones\apps and will now be \\xena\apps

Please make as simple as possible....   THANK YOU

I would probably look for another consultant.

When moving data shares, I would want them moved to a DFS Namespace path so that all future file server migrations are seamless to the clients and no drive mappings or UNC paths need to change.

I usually use Robocopy to copy over data files while maintaining the permissions.

To make sure that people are not using the old shares, change to share permission to deny everyone access once you have cut-over to the new server. That makes sure nobody is accessing the old system. You also need to know how the drive mappings and all other network share references are going to get updated. Once you move to DFS namespace, this becomes a non-issue since the paths don't change as you migrate file servers. :)

If the existing server is a domain controller, you need to make sure that everything is working on the new server. I like to give the new server the old server's IP address so that static DNS server entries remain valid. I also like to like to power down the old server for a few days to make sure everything is working before I demote it as a domain controller.

You need to make sure that print queues, and any other service is migrated over. There's lots of stuff to check, more than what is really possible via a forum. What I have given is the high level steps that a highly competent technical person can understand, but there can be all sorts of subtleties and "small things" that I may have missed, especially since I know next to nothing about your environment. Another consultant is highly recommended. Many Experts on E-E are available for hire.

see this link to show you all the steps involved--skip over the parts that don't apply and even though it says small business server the basic requirement are the same--that is why you should seriously consider getting qualified help However if you do plan to do it on your own I use this guide to help me make sure I keep all the steps in mind

All passwords for company properties the consultant had access to have been changed right? E-mail addresses of record for those properties have been verified to belong to the company too right?

Given the complexity of a migration, it is difficult to give a complete step-by-step of the process.

Did the consultant provide a change log and audit of the current network setup?

When migrating the data files are there custom permissions on the folders being copied? Those would need to be verified.

How are the shares being mapped to the user's profile? The simple way to see where they reside is to right click on a folder under the mapped drive and Properties. The Location property tells where it's at.
