In many cases, Certification expire or are retired. This doesn’t mean that the knowledge is instantly lost, in fact – many times technology is built on itself, therefore that older knowledge and experience is equally valuable.
In the case where my certification have a set expiry or they are obviously out dated, I have listed them here.
