We will migrate our shared proxy server to a new server.

• This affects only a small fraction of managed-servers where the use of the proxy-server is explicitely configured
• Since we migrate the IP address, there is no need for any configuration change on the managed-servers use the proxy-server
• During the migration the system will be unavailable for a short period of approximately 10 to 15min
