Copying server and changing from Apache to Nginx


I have a scenario that i have vps box set up(lets call it VPS1) with apache and certbot. Recently i configured another vps (VPS2) with nginx and certbot. Since second vps setup is better and also newer os (ubuntu 16.04), i would like to install clean ubuntu 16.04 also to the VPS1 and then rsync from VPS2. How do i restore ssl certificates and certbot?

in this scenario you are much better to do a clean install on VPS1 of certbot and reconfigure it

Copying certificates between two servers adds lots of complexities, so for a 2 VPS server set up i would keep things simple and just get each one to issue and manage the certificates they need


Ok. Thanks.
So it is better to exclude certbot and certificate folders if i do rsync? Also there is no problem getting new certificates again for my domain?

yes i would say so

there are rate limits but as long as you are not doing anything to silly you should be ok

We also have a Duplicate Certificate limit of 5 certificates per week. A certificate is considered a duplicate of an earlier certificate if they contain the exact same set of hostnames, ignoring capitalization and ordering of hostnames. For instance, if you requested a certificate for the names [,], you could request four more certificates for [,] during the week. If you changed the set of names by adding [], you would be able to request additional certificates.
