I’m in the process of migrating my instances hosted in an on-prem KVM host to Digital Ocean. I’m very concerned as these machines have never been in a cloud environment and as such doesn’t have cloud-init. I know that cloud-init does a lot of first-time startup stuff, but being that I’m going to spin up a droplet based off of this custom image (the qcow2 from the on-prem hypervisor), are there other ramifications I need to account for?
Will I be able to set the NIC to “dhcp” and be able to bind a floating IP to it or is there additional steps involved?
Will I be able to make snapshot backups of the running instance?
Are there any possible issues with cloud-init interfering with the instance if I install it after I get the instance spun up?
These are Debian Wheezy images.
Thank you for your advice, here’s to a hopefully smooth migration.
