How to copy changed and new files

Our current Windows 2003 server has over 10 shares that have over 500GB data. We will need to copy the data to our new Windows 2008 server which will take over this weekend.

At this moment, the new server is already on the network but cannot be seen by users yet. The plan is that we copy the data today from old server to new server. On this weekend, new server will take over and the old server will retire, we then run copy again, but only copy the changed and new files from old server to new server.

How would you do this?

All modified and new files have "Archive" attribute set. So, copy only them. Robocopy allows for that (use switch /A in syntax)
Robocopy can be downloaded from

map a drive letter to each share e.g x: drive to old share andf then n: drive to new share then use xcopy as a administrator.

xcopy x:\*.* n:\ /y /c /e /d

Thank you both for the prompt comments!!
I think I prefer robocopy which gives logs

When I run robocopy for the first run today, should I use "/COPY:DAT"?

/COPY:DAT is a default mode but I wouls suggest for initial process use /COPY;DATSO
Iw ill also copy NTFS permission and owner information of folders/files

Thanks iSiek.
During the initial process, will a file's "attribute" be reset automatically?
Krzysztof PytkoSenior Active Directory EngineerCommented:
I have to say that I don't remember :/
But if you want to keep "Archive" attribute during copy process, add one more switch which sets it up :)


and each copied file will be set up with "Archive" bit.
