consortium %s org %s attempted to change MSP ID from %s to %

Error message

consortium %s org %s attempted to change MSP ID from %s to %s

What it means

Returned by Bundle.ValidateNew during a config update when an org that exists in both the old and new consortium definitions changed its MSP identifier. MSP IDs are immutable per org name across config updates; this guards against a config that would silently re-alias an organization's identity.

Solutions

1. Keep the org's original MSP ID in the config update
2. If a new MSP identity is required, add it as a new organization and remove the old one in separate steps
