Cloudron Backup for Moving to Another VPS

[leemuljadi]

Thanks all for the response!

@BrutalBirdie is this how to install cloudron with specific version?

wget https://cloudron.io/cloudron-setup
chmod +x cloudron-setup
./cloudron-setup --version x.y.z

and how to check the fresh version installed in the fresh server?
I use Vultr and install Cloudron from the marketplace but when checking with

cloudron --version

it shows

cloudron: command not found

According to the official documentation:
https://docs.cloudron.io/backups/#restore-cloudron

wget https://cloudron.io/cloudron-setup
chmod +x cloudron-setup
./cloudron-setup --version x.y.z # version must match your backup version

If you run:

cloudron-support --send-diagnostics

It will generate all information needed for support and give you an URL to view all the information.
Will look something like this:

I am not sure this type of setup offers a version selection on installation.
Time to get your own hands dirty (= If you need any help, let the forum know.

The marketplace only has the latest version of Cloudron. They don't have a way to select old versions. On Vultr, the cloudron version is 8.3.2

Alright cool thanks guys, I made to install Cloudron on new ubuntu server.

Now based on:
@jdaviescoates https://docs.cloudron.io/backups/#dry-run

I tried several times of this dry-run steps but it will still pointing to the old server IP, any idea why?

and what is gonna happened if I just restore without a dry run?

With dry run, it won't update your DNS. Without dry run, it will update your DNS .

(assuming, you are using one of the programmatic DNS providers)

To access your new server before updating DNS edit your local hosts file (e.g on Linux it's /etc/hosts) to trick your local machine to go to the new IP address.

[leemuljadi]

@jdaviescoates yes I have updated /etc/hosts on my Mac local machine, but seems no effect. Could you please share what it suppose to look like? And after adding the new IP address and domain name run the dry-run it should connect the Cloudron to the new VPS IP right?

The /etc/hosts file is structured in the following way:

IP sub.domain.tld

So lets say your DNS name is my.awesome.it and the official IP from the DNS is 64.26.12.63
Offical DNS can be checked with e.g:

# get IPv4 for Domain from Cloudflare DNS
dig A my.awesome.it +short @1.1.1.1

# get IPv6 for Domain from Cloudflare DNS
dig AAAA my.awesome.it +short @1.1.1.1

Now you have set up a new server with the IP 53.82.33.6. You have run the Cloudron restore with the dry run option.

Now you need to edit your /etc/hosts file and add the following line:

53.82.33.6 my.awesome.it

You should now be able to access my.awesome.it and see your dry run restored Cloudron.
Watch out tho! Browsers have DNS Cache! You might want to use a private / incognito windows to access my.awesome.it to avoid the DNS cache.
One more note.
If you have set up IPv4 and IPv6 for your Cloudron and do a dry run restore and only set the IPv4 in your /etc/hosts file you might still get served the old one if your browser decided it uses IPv6 first.
So it might be best to set both in /etc/hosts.

~Cheers!

@james thanks for the thorough explanations. so I have done this part:
example: 53.82.33.6 my.awesome.it and adding in the /etc/hosts file
but probably still got that browser cache. So I already open it and stuck in this page when opening through the new server IP:

How do I manage this?

[jdaviescoates]

@leemuljadi don't go to the IP go to the URL. If you've correctly done the hosts thing the URL will go to the new IP

Hi all, got issues while restoring to a new VPS, anyone got this before?
