I have a wordpress multisite with several LetsEncrypt certificates. I would like to use cloudflare’s wildcard origin TLS certificate and wish to avoid downtime.
- Do ALL the sites on my multisite need to be on Cloudflare?
- Do I need to revoke/delete all existing LetsEncrypt certificates and how? one by one?
- I have some domains remapped eg Subdomain.mydomain.com is mapped to subdomain.com. Can I add any such domains after creating the original origin cert?
- Can I include a domain before it is mapped? I have live one on a different domain I want to move and avoid downtime whilst I stage it.
