In the SBS2011 to Exchange 2016 migration document, 6. Configure Exchange Server 2016 certificates, a PFX certificate is used in the example. We use GoDaddy certs and they are delivered in a .CRT format. Will this work for the Exchange 2016 migration? If not, how to best generate or convert?

Bruce,
That CRT format is only half of what you need. If you generated a new CSR on the Exchange Server that .crt file can be used to import but if the CSR has been created by GoDaddy you need to ask them for a PFX.
If you already have a working certificate and the CSR has been generated on the SBS you may be able to export the certificate to a pfx file and save the privater key with it. That can be used to import on the new Exchange Server.
