error license server

I would think if it is a new server same DB you may have to re-enter or allow this system through a proxy.  We had to do that on ours to make sure all the web access components like license, upgrade, thwack, customer portal and the like with hooks in to web based services need proxy to allow it.

To do this you go into all settings in Orion web console and then find proxy settings in the product specific settings section.  Then enter the require details for your proxy connections.

what about offline installation ? 

Have you unassigned the license in custom portal before update to new server.

yes, i think i had do it. 
in case if we had do it but isn't worked without taht we know, what we should to do now?

we have open a ticket since friday, and escalate today but no answer. we try to find a answer because is emergency.

It doesn't matter the method of install the license is always and online validation how ever if you cannot get access online you need to go to the license on the customer portal and select the license and use offline activation.  How ever you will open a ticket to customer support not technical support and ask them to deactivate all license as you need to move to new system and activate using the offline option. 

yes we had already this friday, but we have the same problem

Call Solarwinds and refer the ticket number and tell them you are system down due to license issue.
