Rename of FIM Security Groups

Hi,

While installing the FIM, 5  security groups needs to be created on the active directory. Are these five groups needs to created same as mention in the FIM documents

Can we add prefix or suffix any word in the above groups to follow the naming convention.

Like FIMGroup-FIMSyncAdmins-abc. Will it impact if  rename the 5 security groups name before installation  of FIM?

Can we rename the security groups after installation and again run the FIM setup to replicate the new security groups?

Thanks

Harry
