Common use of Upgradeable maintenance Clause in Contracts

Upgradeable maintenance. By default, minor upgrades, i.e., a change from an X.y. to an X.z. version, as well as minor functional upgrades (all of which are hereinafter referred to as "Minor Upgrades") of the TEHTRIS Service are included and subject to the terms of the Agreement. Interventions relating to Minor Updates may make all or part of the TEHTRIS Service temporarily unavailable. TEHTRIS shall not be liable for any impact of such unavailability on the User's activities. Evolutionary maintenance is scheduled by mutual agreement with the User. TEHTRIS reserves the right to delete features in order to adapt to global developments in information technology. The frequency of evolutionary maintenance is about three (3) per year on average. The upgrade to a major version, i.e. a change from version X to Y involving a substantial change in the operation of all or part of the TEHTRIS Service, may be submitted to the User through a new quote when special conditions are needed. User may refuse to upgrade to a higher major version for a period of three (3) months from the new major version’s public availability. At the most, at these three (3) months period’s end, the Parties agree to meet in order to define the transition to the new version. As it is not advisable to maintain the old versions in operational condition, the User is advised to apply the proposed changes in order to continue to benefit from the advanced security features.
