Calculate a maintenance window duration for update Deprecated

Deprecation notice

The maintenance window duration calculator is deprecated. Starting from MOSK 25.1, cloud operators should use the ClusterUpdatePlan API instead. For details, refer to ClusterUpdatePlan resource.

This section provides an online calculator for quick calculation of the approximate time required to update your MOSK cluster that uses Open vSwitch as a networking backend.

Additionally, for a more accurate calculation, consider any cluster-specific factors that can have a large impact on the update time in some edge cases, such as number of routers, frequency of CPU, and so on.
