Changing hostname of SAP system

Hi everyone,

We are in the process of standardizing our naming convention for the SAP servers. What impact does a server rename have on the SAP servers?

As far as i know that the hostname is stored in the default,start and instance profiles.

We are using SQL Server. R/3 version is ECC6.0

What are the activities to be performed to get the SAP instance working after the hostname change?

Thank you,

-Vinod.
