Yes. You can upgrade/downgrade your Virtual Private Server at any time.
However, if you want to downgrade your unmetered shared hosting account, you will need to move your files to another server.
This is due to the fact that USH plans are located in totally different servers so that we can offer better quality for the more expensive packages. The more a customer pays for an unmetered shared hosting account, the more powerful the server the website is hosted on.
However, for the most part, dedicated servers cannot be downgraded due to hardware restrictions.
You can always order a new server and cancel the current one. All upgrades on HDD and RAM are limited to port availability in the motherboard and related hardware configurations.
It is always best to coordinate a downgrade/upgrade with abdicar.com's technical experts through the Customer Portal.
