Hi I have VPS1 running domain.com . Using virtualmin I created a let’s encrypt ssl certificate that is renewed automatically every x months and all is good. Now I want to migrate domain.com to VPS2 (different IP). At first, domain.com will still run on VPS1. After I will finish the setup, I want to…

It makes best sense (zero downtime) to prepare VPS2 fully before changing the IP of any names. Otherwise, the IP will point to a system that isn’t prepared and there may be some “downtime”. To that end, you could copy the entire LE folder from VPS1 to VPS2 along with your web server configs. That…

Thank you for your reply. My plan is to prepare VPS2 completely and then go to the registrar and update record A. I don’t remember exactly my steps when issuing letsencrypt on VPS1 but back then I didn’t have any parallel VPS and no worries about downtime :slight_smile: Files and folders I know ho…

[image] amoss: ensure “copy” brings all the right links and permissions”? Presuming you will be using TAR to "zip and copy", things like: --keep-directory-symlink -p, --preserve-permissions, --same-permissions -P, --absolute-names Whatever you do, you need to compare the files in VPS1 wit…

[image] rg305: To that end, you could copy the entire LE folder from VPS1 to VPS2 along with your web server configs. You did read he used/uses VirtualMin, right? I'm guessing it's going to be a little bit more difficult than just copy a bunch of files over.

Let’s see if I got it right: In virtualmin I set it to use letsencrypt, it does all the work, create the folder, create the files, create the certs and all is good. I set it for domain.com and www.domain.com even though domain.com is still pointing somewhere else. It should be ok, no? does lets encr…

Soon I will need to start the migration and I will have a short period of time to do that, please let me know if I’m missing something with my previous description, specially this parts: Can I create a certificate on VPS2 for a domain that resides on VPS1? Assuming I can, changing the A RECORD fro…

Thank you for the links. So I will need to do something (http or dns challenge) to prove I’m the owner but VPS1 will still be active so the challenge will “pass” but it won’t once I’ll do the switch. If I understood the articles correctly, it means I will have to do the migration only after changi…

OK, I read here http://nateserk.com/2019/tech/migrate-letsencrypt-ssl-certificates-to-a-different-server-guide/ and it’s all sound clean and simple, except for one thing: I’m using virtualmin that has its own letsencrypt mechanism for it so I didn’t understand if I should do all the above before or …

That’s a very good question. I’m not sure the regulars on this forum have (much/any?) experience with Virtualmin. Perhaps it’s a good idea to ask that on a Virtualmin forum?
