Only accurate current facts should be used. Review the duties, employing entity and terms rather than treating a date change as a complete update.
Preserve useful history without presenting it as current evidence
Explain material differences and identify the operative offer. An old letter may help describe the past but should not misstate what the applicant will now do.
A short letter on institutional letterhead stating that the former school merged into the current one on a given date, that the program continued, and that the transcript reflects the same records does more than several pages of applicant explanation. The failure worth anticipating is a history that contradicts itself in small ways: a letter dating a role from January, an admission record showing arrival in March, a transcript issued under a former surname. Where the qualifying path relies on experience rather than a degree alone, that experience needs evidence more durable than a résumé line: dated employment letters describing the actual work performed, or project records naming the person and the period. The portfolio supplements the credential and employer account; it does not replace the applicable degree or diploma/certificate-and-experience requirements or prove that unrelated production duties are professional design.
