Renewal creates a brand new key with a brand new certificate,
which can (and often does) have an entirely new chain.For

Server cert 2014->Big Name Intermediate G2014->Big Name Root CA R2010
Server cert 2016->Big Name Intermediate G2016->Big Name Root CA R2015

Also, it is possible to have more than one chain leading
to the same server cert, with the possibility to
reconfigure the server to send a different one of those

Server cert->Intermediate CA1->Intermediate CA2->Root CA1
Server cert->Intermediate CA1->Root CA2
