2. Start a new project and complete the first pass of migrating data.

3. Complete the project, copying the delta and recreating the shares on the destination Server 2012 R2.

4. Decommission the legacy file servers:

- Delete computer accounts
- Delete DNS records

5. Add the names of the legacy servers as additional names to the destination server, so users and applications can access the existing share paths without any changes:


NETDOM COMPUTERNAME FS-12 /ADD FS1-03.netometer.com

NETDOM COMPUTERNAME FS-12 /ADD FS2-03.netometer.com

NETDOM COMPUTERNAME FS-12 /ENUM

restart-service LanManServer

ipconfig /registerDNS
