Instance relocation (lemmy.click)
submitted 1 year ago* (last edited 1 year ago) by Lodion@lemmy.click to c/lemmy@lemmy.ml
 

I'm planning to move my instance to a new VPS provider that will allow me to scale more simply.

Has anyone done this already and can sanity check my plan? My current setup was spun up using the ansible playbook here.

Current plan is:

Lower DNS TTL to 60 seconds (already done)

Shutdown on current VPS: docker-compose down

backup /srv/lemmy// and copy to new host

sudo tar -zcvpf backup.tar.gz /srv/lemmy//

scp backup.tar.gz user@newhost

update dns A and AAAA records, wait 1 minute, verify DNS has updated

run ansible script

Shutdown on new VPS: docker-compose down

restore backup to /srv/lemmy//

Startup on new VPS with restored DB etc: docker-compose up -d

test

destroy old VPS

Increase DNS TTL to 86400

Anything I've missed? :)

Nah, part of the playbook sets up the initial Lets Encrypt certificate... so DNS needs to point to the new VPS. And the hostname needs to match the existing instance as it is referenced in the database.

Doesn't matter now anyway, I went a different route :)

How'd you end up migrating it?

[–] Lodion@lemmy.click 1 points 1 year ago

I didn't, I spun up an entirely new instance.
