As I understand you want to remove nodes and add new - with new names. In database/accounting this names have no special format, they are just "strings". So... old nodes (old names/ip's) from slurm.conf are going to be down and you need to add new entries to slurm.conf, but.... maybe I'm not getting what the problem is..? cheers, marcin
