How to change Node/SIA name in BO 4.1

Hi All,

We have installed bo 4.1 SP2 Patch1 on machine called abc but due to some reasons abc machine name has changed to xyz.

Since, we change the system name I thought we should sync our bo application naming conventions with newly changed system name xyz.

Please tell me the steps to change respective configuration files and location of those files.

your valuable advises will be highly appreciable.

Thanks

KK
