Many webshops deal with visitor peaks, for example during the Christmas season. Traffic generated by customers is great, but may lead to performance issues if the number of visitors is too high. We advise webshop owners to take precaution and upgrade to a bigger Hypernode with more resources in advance.
A big advantage of our Hypernode plans is that you can up- or downgrade your plan at any time! You are not bound to contract terms, you only pay for what you use.

Up- and Downgrade your hosting plan
If you ordered your Hypernode hosting plan via Hypernode.com, please change your current plan via your control panel.
- Log into your control panel via my.hypernode.com
- Go to the Billing portal
- On the Billing portal, select your current plan
- Then click on Edit subscription
- Select the desired Hypernode plan from the drop-down menu and confirm your choice by clicking on Update subscription
Your subscription will be changed immediately; you will only pay for what you use.
Pay Per Day
Do you only need a larger Hypernode for a few days? No problem! You can downgrade to your original plan as soon as the larger Hypernode is no longer needed.
If you upgrade your Hypernode to a bigger plan for a single day, only 1 day will be billed. This way you can upgrade for an event, mailing or sales action without being bound to a monthly plan for the rest of the month.
Just upgrade your Hypernode plan a day in advance, run your event or sales action and as soon as the number of daily visitors has normalized again, downgrade your plan. You only pay for what you use.
If you upgrade your Hypernode plan and change it back within 2 hours, no additional cost will be incurred.
This way, if you up- or downgrade your Hypernode by mistake, you can always undo your action without extra costs.
If you want to do a quick test or ensure yourself the bigger node is big enough for your expected traffic increase, this can be done during the 2 hour reflection time.
Recommended Checks Before an Up -or Downgrade
Up -or downgrading your hosting plan is very easy, but be aware we will automatically migrate your shop to a new (Hyper)node, resulting in some downtime and a change of IP address.
No Change of IP Address With Dedicated IP’s – 2 Exceptions
When upgrading or downgrading a Hypernode plan, we first create a second node, migrate your shop to this new node and then remove the old one. Hypernodes have a dedicated IP, meaning the IP-address of your Hypernode does not (!) change when you change a Hypernode plan. However, there are 2 exceptions.
- Changing between Professional and Excellence plans will lead to an IP-change because you will change providers (e.g. Combell OpenStack to DigitalOcean to Amazon and visa versa)
- If you request your node to be booted in a different region (datacenter) the IP-address will change as well.
Right before the migration is finished, we email the technical contact the new IP address.
If you think you might switch between Professional and Excellence plans in the future, we recommend you to move your domain(s) to Byte so we can handle the DNS of your domains to avoid downtime. Or, use the DNS settings as explained in this article.
Make also sure to keep a list of payment providers, firewalls, local DNS servers and other services that depend on the IP address of the Hypernode, so you can quickly change the IP address if needed.
Downtime During Upgrades
If you have a very large database or a highly utilized Hypernode, upgrades can cause some errors due to deadlock errors on your database or long running PHP processes reaching timeout values.
Make sure you do not schedule up- or downgrades during peak hours and always check Magereport Premium or the command line to ensure yourself no product exports and long running crons are currently active.
Ensure yourself no mailings, TV commercials, social media advertisement and other traffic generating events are started. Always upgrade in advance!
SSH Access During Up- and Downgrades
During the up- or downgrade we disable SSH and FTP access to avoid new file changes that are not copied to the new server.
Make sure not to add product changes, upload images, or change settings in the Magento admin backend while a migration is executed.
How an Up- or Downgrade is Managed (Hypernode Professional and Excellence M-XL)
Up- and downgrades are a fully automated process which consists of provisioning a completely new Hypernode of the specified size, copying the data from the old Hypernode to the new one and updating the DNS. To perform the data synchronisation, we first perform a pre-sync where we copy the data to the new node while the old node continues functioning. Up until this point nothing has changed from the perspective of the original machine.
When the complete dataset has been synced to the new instance, we stop the services on the old system to prevent new orders from coming in and then perform a second quick synchronisation to make sure that everything that has changed since the initial synchronisation is transferred as well. After that point the DNS is updated, the services are started on the new machine and the migration has been completed. After that, we decommission the old node.
Downtime depends on the size of the shop (the amount of data which needs to be synced) and the TTL of your DNS.
How an Up- or Downgrade is Managed (Magento Excellence 2XL and up)
As explained above, a shop occurs downtime when up-or downgrading (only during the second sync). Downtime may only be a couple of minutes for small shops, but a data sync in case of (very) large shops may take a while, resulting in longer downtime. For Magento Excellence 2XL nodes and larger we have therefore implemented a very cool way of handling up -and downgrades, resulting in very little downtime.
Upgrades and downgrades between the Excellence 2XL, 3XL and 4XL products keep the same cloud volume during x-grades instead of copying the filesystem from the old instance to the new one like before. This speeds up the data transfer step in migrations from multiple minutes (variable depending on the amount of data and rate of change on disk) to less than one minute for these specific node sizes.
