Logic Pro 7 & earlier New Logic board in machine

#1
Sorry for the seemingly OT here but I'm wondering something: if one replaces a Logic board in a Mac Pro, does that change the machine ID? The reason being I am wondering which manufacturers plugins would have to be reauthorized? I have too many plugins to reference them all on this particular machine but if anyone knOws off hand which manufactureres may cause problems (if any) I'd be much obliged. I know dongle based plugs will be fine but what about N.I., Spectra, etc.?

Cheers,
