Yes. Our platform supports easy upgrading and downgrading of systems on-the-go, so you can upgrade/downgrade as needed. 

Please keep in mind the following:

• Some types of upgrade require a VPS reboot.
• Upgrades and downgrades can be completed at any time within a billing cycle, and will be pro-rated according to the days remaining in the cycle. Account credit will be given in the case of a downgrade.
