I take it you mean you are rehosting a database as well as upgrading, if it was only being upgraded then nothing would need to change, if it is being rehosted then read the following section in the documentation - Rehosting a Database
There are server names and hosts used during installation and configuration. Where is the IP address used during configuration or installation of 188.8.131.52.
You mean to say, Oracle database is with server name, Hyperion configuration done by IP address ? If yes, then check Same IP address is there or not, able to ping or not.
That's it. Do not need any changes in Hyperion.
