This is Miraheze's migration plan for the new infrastructure per T6787.

Definition of immutable
	* True: doesn't contain data that must be migrated
	* False: contains data that must be migrated (e.g. mariadb/graylog/gluster)

Prerequisites
	1. Purchasing the new servers (cloud4/cloud5) and IPs, action: SPF
	2. Installing proxmox on new servers, action: paladox

== Migration process ==
cloud4 and cloud5 will be installed. Fresh migration: no 'live migration', but spinning up new instances.

	* cp9
		* Planned replacement: new OVH VPS cp12, to be bought
		* Immutable: true
		* Process: spin up new cache proxy, change DNS config, change cache proxy IPs in nginx.conf & LS.php
		* Action: SPF
	* gluster1
		* Planned replacement: gluster3 @ cloud4
		* Plane space upgrade: 1tb
		* Immutable: false
		* Process: Going to rsync all date to the new volume (in order to stop using stripe (sharding))
		* Action: paladox
	* gluster2
		* Planned replacement: gluster4 @ cloud5
