So, is the nss backend no longer supported?

I am dealing with an environment where most of the time users are using 
there existing Unix accounts across multiple Unix clients via NFS with 
several TB of data and associated backups all using their existing UIDs. 
I was hoping to do a quick switch-over to the new system with minimal 
disruption. Changing everyone's UID would involve a major disruption.

Thanks,
