Hi,

Currently my file server (1TB of data) is still is a 32bit Windows 2003 server. I'd like to use a 64bit W2008 R2 server instead now. How would I ideally transfer the data without loosing the permissions on the shares, folders, etc?

Thank you

Hi,

For data, I would suggest using robocopy, it has options to copy data with security and file attributes. And it has also a sync / mirror option. So after the first copy you only have to sync the changed files at the migration moment.

Look here for all options: http://technet.microsoft.com/en-us/library/cc733145.aspx

For shares, you can just export this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\Shares and import it on the new server. After a restart you will see all shares on the new server.

Hi, thanks. But Windows 2003 isn't among the 'applies to' operations systems ... ? How about FreeFileSync? Do you know that one?

you can just run the command from the 2008 R2 server an example:

robocopy \\server2003\d$\datafolder \\server2008\d$\datafolder /E /B /COPYALL /SEC /MIR /R:3 /W:2

ronnypot:

and what would the sync command (that I'd run after I have copied all the data to sync the couple of files that might have changed during the copying) look like? thanks!

You can just run the same command as in my exameple the /MIR function is for just update only changes.

So first time it will do a full copy and afterwards only changes

Copying it with robocopy works so far, except for the users folders on my file server ... the domain admin doesn't have access on those by default ... so robocopy gets 'access is denied' messages ... any suggestions?

Another weird thing though with robocopy:

When I start a second robocopy command (after having stopped the first one) with a different source and target folder then this new target folder quite immediately disappears from Windows Explorer!? Although it is still there, in a sense, since I can access it by entering the full path. Same for the command line: it doesn't get displayed when doing a 'dir' but it can be accessed with 'cd' ... ????

And after having aborted the robocopy command the 'NT Kernel & System' still takes 50% of the CPU?

Update:

So the robocopy didn't work for all the files for some reason ... so I had to abandon that option.

Finally I had the idea I should have had all along: I've simply restored the virtual disks as new disks on my new datastore and attached them to my newly configured server! Works flawlessly :)

ronny: the problem with robocopy was that some of the folders did not have the 'administrator' in their security permissions that copying the content didn't work. and then there was the strange issue of the 'disappearing' folder when I started a second robocopy command ...
