    Hi there,

    Is it possible to do a direct migration between a Windows 2000 DFS environment in one domain (Domain A), which presently holds ALL DFS configuration and also hosts the NAS-connected data, to a Windows 2012 R2 environment (Domain B) on a different domain, with a two way trust established.

    Are there are schema differences, DFS version setup or other gotcha which needs special consideration?

    Additionally, at present users from Domain B can access the Win2000 DFS namespace via the trust and a set of security groups replicated via Quest Migrator between Domain A to Domain B.  If after the DFS migration Domain A is decommissioned and the shares with the data brought into Domain B, what access permissions issue could potentially be encountered?

    This is a new environment for me and still picking up how it's all configured, but would appreciate any thoughts on the above in the meantime.

    Regards,

    Martin

    Hi Martin,

    May I ask you mean the domain A is DFS  2000 mode, right?

    What's the OS for your old dfs server?

    You want to achieve the dfs domain migration? Is the dfs domain based dfs ? If so, for DFS configurations you may have to recreate them as the domain name is changed. And I also suggest you could reconfigure the permission manually.

    And according to your description, Domain B could access the old dfs server in domainA at first. But after migration, dfs namespace should have changed. Besides, you have moved to the new server 2012. So for domain B users, they access the new dfs server in the same domain then. It is recommended you reset the permission for the users in such scenario.
