Symbiosis migration guide
So, you need to migrate from an old Symbiosis server to a new one? You’ve come to the right place! This guide will walk you through how to migrate your whole server, including databases, websites and mailboxes.
Your old server can be any kind of server (ie, Legacy, Cloud, or Dedicated), as
long as it’s running
Symbiosis 6 or above. If you’re not sure what
operating system you’re running, just give us a shout.
In this guide we’ll call the old server
- Create a Cloud Server in just a few minutes! Pick
Symbiosis 8or later as your operating system. Note down the
adminpassword you’re given!
- The storage space on your new server should be the same or larger than your old server, otherwise you might not have enough space.
In this guide we’ll call the new server
Access to your servers
- You need access to your old and new servers using an SSH-client like PuTTY. The command-line can be scary, but this guide will walk you through every step.
- If you get stuck or aren’t sure about anything, just give us a shout.
Check web application compatibility
The versions of PHP and MySQL might be different on your new server. Ideally, check with your web developers whether or not your websites will be compatible with your new server before you continue.
Symbiosis 9 (Stretch): PHP 7.0 and MariaDB 10.1 Symbiosis 8 (Jessie): PHP 5.6 and MySQL 5.5 Symbiosis 7 (Wheezy): PHP 5.4 and MySQL 5.5 Symbiosis 6 (Squeeze): PHP 5.3 and MySQL 5.1
Let’s get started!
There are two phases:
Testing the waters. Your old server and websites remain as they are, but you can copy your sites to a new server and test whether they work. There’s no downtime really, so this phase is almost risk-free! You can back out at any point, delete your new server, and nobody will have noticed a thing.
Making the switch. Here you change the DNS records for your websites to point to your new server’s IP address. You might have some downtime!
