Change ip address on server

Hello,

My testing BOA server is on Rackspace Cloud Server.
My server BOA worked but... to save money... I wanted :
- create an image of server
- delete it
- and rebuild it from the image i made.

Course, the server has changed IP address.
How to configure the new address ?

I edit the .barracuda.cnf, replaced the _MY_OWNIP variable and run barracuda up-stable.

But, is that enough?

I seem to have a problem on the server because the verify tasks for sites and platforms no longer starts.
They are still waiting...

Thank you for your help.

Stéphane.
