All upgrades are free.
For our SaaS hosting and enterprise clients, all upgrades are performed by our team. Frequency varies but the majority of upgrades occur during off-peak hours. If you are self-hosting and do not have a monthly support plan, you would manage this yourself unless.
Downtime is usually just a few minutes at most and will be scheduled at off-peak hours whenever possible. We will contact you in advance if longer downtime is required.
