Updates between major versions of COYO (version 9, version 10, version 14, etc.) cannot be skipped. This means that a major version can’t be bypassed.
If, for instance, you’re on version 9.0.8 and want to update to 14.11.0, please first perform an update to the last major version for 10 (10.0.38) before finally updating to the major version for 14. The main reason for this is database migrations, which are necessary for certain versions. You can find detailed instructions on updating in this article.
