You can purchase Support and Updates anytime. If you purchase before your included Support and Updates expire, they will be good for a year from the time the included Support and Updates expire. There is also no penalty for purchasing Support and Updates after your included Support and Updates expire, in which case Support and Updates will begin immediately and be good for 1 year.
Can I upgrade Blesta if my Support and Updates have expired?
If your Support and Updates have expired, you can only upgrade to a newer patch version of your current minor version. For example, if you are currently using Blesta version 4.5.0, but Blesta has released version 4.5.1 and 4.5.2, you can upgrade to either 4.5.1 or 4.5.2 even if your Support and Updates are expired.
You will need to renew your Support and Updates if you want to upgrade to a newer major or minor release. A new major or minor release is any version of Blesta where either of the first two sets of numbers differs from your current version. For instance, if you are using version 4.5.0 of Blesta (i.e. major version 4, minor version 5, patch version 0), you cannot upgrade to version 4.6.0 or 5.0.0 without current Support and Updates.
