We are in the middle of a domain migration and are going user by user in terms of migrating outlook, profiles etc.
In the meantime all the servers including File Servers need to be migrated to the new domain. What is the best way to give permission to both sets of domain users? Meaning, once a user is migrated to the new domain he will no longer have access to the files in the file server so <newdomain>\<newuser1> needs to be added to the file server and similarly for all the groups too!
Since users will be done one on one we need to have both sets of users (already migrated and yet to migrate) to have access to their folders and other shares on the file server.
We have copied all the Users and Groups in the new AD and we are planning to manually add the new domain users and groups to our file server shares. Is there a better way of doing this?
Any ideas greatly appreciated! Thanks.
