How to ensure a smooth transition to Let's Encrypt SSL Cert?

Hello!

I've got LAMP running on Ubuntu 14.04 and almost a year ago I installed SSL (TLS 1.2) certificate for my web server, so my site would only run under HTTPS protocol. On October 8 the certificate expires. And from now on I want to install and use Let's Encrypt. They have pretty good tutorials on how to use Let's Encrypt, so (hopefully) I won't have any issues with it. But I don't know what to do now. Must I wait till after my old cert expires? Or should I go ahead and proceed with Let's Encrypt installation ASAP? If the latter, then another question arises. How to get rid of the old cert? I mean, it's probably NOT a good idea to use two of them side by side. In short, too many things I don't understand.

I would start now. Familiarize your self with the whole process then try and make the switch. If something goes wrong you can put things back while you figure it out, because your current certificate is still good.

If you wait until your current certificate expires, then you run into problems setting up lets encrypt for the first time. You will have an extended period of people getting browser warnings while you try and figure out the problem.

So what's the correct order of things? First, to delete the old files? I placed .crt and root_bundle.crt files in /etc/ssl/certs directory and a .key file in /etc/ssl/private directory. Other than physically deleting those files, do I have to run any specific command in the terminal or something? And then to install Let's Encrypt?
New cert from what I understood shouldn't be put like a file, it's somehow automatically works. Not the way it was with the old one...
Also in a file /etc/apache2/sites-available/000-default.conf there're 3 references to my old cert's files:

SSLCertificateFile /etc/ssl/certs/my_domain.com.crt
SSLCertificateKeyFile /etc/ssl/private/my_domain.com.key
SSLCertificateChainFile /etc/ssl/certs/root_bundle.crt

So what to do with those links? To comment out them? Or update with a new files that would be created by Let's Encrypt etc.?
