Migrating DLO server from Windows 2003 to Windows 2008

Hi,

I must migrate our DLO servers 6.1 (windows 2003+SQL 2005) to a new platform that will be Windows 2008 R2 with SQL 2008R2 and DLO 7.0.

We have near 1000 users on one DLO server, and 500 users on the second server.

Is where a best practice for this operation ?

My idea was to install two new 2008 servers with SQL 2008 R2 first.

Update the old DLO 6.1 servers  to 7.0 in order to have the same version.

Import the database of the old servers with:

> DLODBUtils -backup

Remove the old server, insert the new server in AD, change the servername (in order two have the same name as before).

use >DLODBUtils -restore, in order to restore all the configuration of DLO in the new server.

Please give me your point of view about this process.

Thanks.

Ismail.
