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 ? 

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.

So you activated offline and it worked but still saying the same error?

please confirm if you have tried to already activate this new instance if it said it was successful or not?

no, was an other problem, now it's working; all is Ok

What was the other problem?  How did you get it fixed finally? Thanks.
