The time it takes all depends on the upgrade type and game server:
Slot or CPU process priority upgrades for game servers using our TcAdmin control panel is done automatically within a few minutes and effective immediately. Ensure you upgrade during a down period as it can restart instantly.
Slot of CPU process priority upgrades for our Space Engineers or Medieval Engineers servers are done manually and will be done as soon as possible subject to staff availability.
RAM Upgrades for Minecraft are automatically within a few minutes effective on the next restart.
For other upgrades such as location changes and hardware upgrades for any game server. These are done manually, after order, we will contact you to arrange the change at a suitable time.
If its a location or hardware change, these will take 1-3 hours to move everything over to the new server depending on the size of any mods, your map etc (all your configuration/saves etc will be transferred). Location changes do require an IP change.
