How to start an already used lemmy instance?

When moving my lemmy instance to another server, how do i make shure that the instance starts up again? I used the lemmy-Ansible method to setup my instance. I use digitalocean to host my instance, and when creating a snapshot to move the server location, the instance would not work. Luckly i still had the original droplet intact. I am very new to server management, any help would suffice. Thanks in advanced!
