How to execute wordpress instance migration seamlessly (Droplet: Ubuntu 20.04 - OpenLiteSpeed Wordpress)

Hey guys,

I’m just trying to figure out what are the remaining steps for a graceful transition between my old web host and my new droplet.

Here’s what I’ve done so far:

• Setup my droplet to target my subdomain (do.mydomain.com)
  • Also used Certbot automatic setup at when I first launched the server to issue certificates for this subdomain.
• Copied my Wordpress DB and files.
• Updated config files and php.ini.
• Tested that everything works fine through do.mydomain.com
• Installed OLS plugin on the new Wordpress instance and setup everything

So that’s the base setup. Now I began the migration but after struggling with certbot, I had no choice to stop for today ( Error creating new order :: too many failed authorizations recently: ). I’d like for everything to go well tomorrow then I try again.

I seem to be lost when it comes to make sure my droplet is ready for the main domain name (leaving do.mydomain.com for just mydomain.com).

I never used certbot before this droplet. Never setup a web server beforehand to be honest. Moving from a CPanel installation that will stay alive on the other host just because it’s cheaper than a licence and my emails are using CPanel forwarding features.

So what I done so far (all on the droplet):

• Changed home and siteurl in wp_options in the DB for mydomain.com instead of do.mydomain.com.
• Added listeners for www.mydomain.com and mydomain.com to my OLS admin panel (edited the ones already there for do.mydomain.com and just added the two domain names above).
• Edited my Domain Registrar A Record for mydomain.com to point to my droplet IP’s address.
• Ran certbot certonly, specifying “Places files in webroot” (which is the same and only webroot as do.mydomain.com, /var/www/html/). Specified the domain name mydomain.com a few times, kept failing, so I specified the domain names mydomain.com, do.mydomain.com and it gave me the “Expand certificate” option, which I selected. Finally got the “Too many failed authorizations” error which is where I’m at now.

For the time being I changed back my A Record for my main domain name back to my old web host since I’m having about 100 concurrent visitors all the time…

I really need the switch to be seamless and the certificate thing fixed. Any tips for tomorrow ? Anything I forget ? Thanks in advance for your help.
