We have a forum running in AWS, on a custom domain with SSL via LetsEncrypt and we’re looking to move to Digital Ocean, ideally without downtime. Is there a recommended best practice as I’ve encountered a variety of problems?
I first tried setting up the new instance and enabling LetsEncrypt but this caused all sorts of problems (e.g.
SSL: error:0909006C:PEM routines:get_name:no start line:Expecting: TRUSTED CERTIFICATE) – presumably because I was trying to set up the new instance using the same domain name in the configuration as the existing live site.
I then tried setting up the instance without SSL (but with the instance configured on the same domain name) and restoring a backup from the live site. This time the restore process failed with what looked like issues around the domain name.
Setting up a new instance on a new domain is really easy (thank you! ) but trying to create a new instance that I can then just do a DNS switch over to in order to migrate appears to be really hard. Unless, that is, I’m just doing it wrong!
Any help would be appreciated.
