Moving an Ubuntu 16.04 VM on Vultr from one data centre to another via snapshots

by

This guide will show how you can move an Ubuntu VM server domain between Vultr data centres via snapshots.

I have a number of guides on moving away from CPanel, Setting up VM’s on AWS, Vultr or Digital Ocean along with installing and managing WordPress from the command line. Sometimes you need to move a sever between locations and/or upgrade the server (to have more memory t install WordPress).

Moving an existing Vultr server

If you don’t have an Ubuntu server click here (follow this guide).

Login to Vultr and specify a source server, click Snapshots and click Take Snapshot.

Make snapshot

Wait for the snapshot to finish (It may take 1 hour).

Snapshot Started

Great, the snapshot is done.

Snapshot Ready

Now I can create a new server (in a different data centre).

Add

Deploy New Instance

Choose a location (Australia is at capacity, so I’ll deploy to Silicon Valley then move again in a few weeks), choose the snapshot to restore, choose a plan, I enabled IPV6/Auto Backups and Private Networking.

TIP: The password for the server will be the same as the source server so write it down.

Deploy

Click Deploy Now

Deploy

After a few minutes, you can see the new servers IP address, you can log in to your domain name provider (in my case Namecheap) and update the target IPV4 and IPV6 address.

You can find IPV4 and IPV6 addresses by opening your server, clicking settings then IPxV4 or IPV6.

ip

You will need to update Vultr DNS settings (login to Vultr, Click Servers, Click DNS then edit your existing Domain DNS entry).  Add you’re new serves IP addresses.

Vultr DNS

Update: I added an IPV6/AAAA record too.

Wait for DNS Replication

Goto https://www.whatsmydns.net/ and check the global DNS propagation for your new domain’s server.

DNS Propigation

If you are happy that the server has been migrated (snapshot restored) and that the domain DNS is pointing to your new server you can delete the old server in the Vultr server list.
