security groups naming convention in FIM 2010 R2

Hi,

I am using five security groups for Installing FIM Synchronization Service Manager the automatically pick these groups when installed the FIM Synchronization Service Manager

FIMSyncAdmins,

FIMSyncJoiners,

FIMSynchOperators,

FIMSyncBrowse,

FIMSyncPasswordSet

Everything is  working  fine bot now for naming Convention clients wants to change these securities groups name.

So I want know that five security groups name should be same as above name or can we change  these security groups name for naming convention.

For this what steps should be follow in running Environment.
