Group ' ' not found for old profile.

Error message

Group '{oldProfile.Group}' not found for old profile.

What it means

ReplaceProfile first removes oldProfile from its current group; the lookup of oldProfile.Group in LoadedProfileFileData.Groups returned null, so the old profile is not actually present in any known group. ReplaceProfile throws rather than leaving the profile file in a half-updated state (old profile neither removed nor new one added). This is a sentinel consistency check against stale or foreign ProfileInfo objects.

Solutions

1. Pass the ProfileInfo instance obtained from the loaded profile data, not a detached/stale copy.
2. Confirm the old profile's Group matches an existing group name exactly (case/whitespace).
3. Use GetGroupByName or GroupExists to verify the group before calling ReplaceProfile.
4. If the profile was already moved or removed, skip ReplaceProfile or add the new profile directly instead.
