Advice on QNAP TS509 Data transfer

Hi Experts, we have a client with a QNAP TS509, we have inherited this when we took the network over.
The issue is that it has been set up with intricate links between spreadsheets etc. Is their an easier way to move this data intact to a new 2012 domain controller/ File server, or would it be safer to move to a more up to date QNAP?
thanks in advance.

I would assume you'd have the same issue whether moving it to a server or another QNAP as it's more the file and folder structure you want to preserve.

Personally I'd setup identical shares/folder structure and permissions on the new device, copy over some documents and test the links to see if they work - if they do then arrange to migrate the live data over (using something like robocopy).

Hi Andy,

What I was thinking after speaking to a few more people is this:

Setup a new CNAME record in the local DNS entries on the DNS server to the new data location with the same name as the previous location. Move the shares using something like robocopy or totalCMD. That way when the clients query the old name, they are sent to the new name.

In theory it should work, however theory usually goes out the window in practice.

Any thoughts?

Yeah, in theory that should work though you'd need to ensure that there are no other dns entries for the old device using that name (i.e. if DNS auto creates a record for the device), otherwise confusion will ensue on the machines and data will be saved to both locations.

Plus (and I've personally had this happen a few times which is why I don't like messing with DNS in this way for shares) -  if DNS does not update on some machines correctly, some users will be still using the old share.

The other thing to watch out for is users that use the IP address rather than the hostname.

Personally I'd do the following:

1. setup new folder infrastructure and test access rights, etc.
2. Inform all staff that on a particular day/time they MUST start using the new shares. Give them time to update any shortcuts/manually mapped drives/etc.
3. Remove all permissions for staff to access the old shares prior to copying the data (so only leave an admin access for yourself).
4. Use the admin permission to copy data from the old share to the new one.

This method prevents any access to the old share by users while data is being transfered over (and thus reduces the chance of data being saved to the old share and getting missed). Plus, after it's copied they can't accidentally edit data on the old shares.
