If you look at the Installation Guide that ships with 12.2.4 and 188.8.131.52 Demantra, you will see Windows 2012 is also supported. You can just install the Administrative Tools on the new server.
I have seen clients upgrade Windows 2008 to Windows 2012, leaving the Demantra installations intact. Most Windows Admins prefer to do a fresh installation though.
Thank you for the reply. can you please provide steps for 184.108.40.206 Administrative Tools on the new server without changing anything on Solaris machines. iam new to Demantra. please help.
You need to install demantra (Software only) only on new server. I will help you to setup.
Let me know if you need any other help.
