Straightforward guide on moving from one v5 server to another

I am on version 5.8.57, can’t update because next revision requires a higher version of php than my current Ubuntu server updates to.
Tried to upgrade the OS and this resulted in failure to boot. So I rolled the virtual machine back to a previous snapshot.

The VM is Ubuntu server 20.04.5 LTS, planning to deploy a fresh install of 22.

All I need is a server move checklist with any available documentation linked. Is there such a guide someplace, before I start researching this?
I have documentation on my previous install procedures and the move from v4 to v5, which also ended up requiring a server move. But if there is a concise set of documentation for deploying a new self hosted server, then migrating data from an existing v5 server into it, that would save me some digging.

Thanks -

Hi,

You just need to copy over the database using mysqldump and the .env file.

I found this guide online which may help:
