Yokohama(+) Upgrade: Increase in the upgrade time for reparenting SM M2M Task Dependency [sm_m2m_task_dependency] table to SN Task Dependency [sn_task_dependency_m2m]The “SM Core” application upgrade to Yokohama may extend the customer upgrade maintenance duration due to the following: An extension of the SM M2M Task Dependency table (sm_m2m_task_dependency) to the SN Task Dependency table (sn_task_dependency_m2m) from the Task Dependency core plugin.In the SM M2M Task Dependency table (sm_m2m_task_dependency), the fields “upstream_task” and “downstream_task” will be migrated to two new fields, “parent” (Predecessor) and “child” (Successor), sourced from the parent SN Task Dependency table (sn_task_dependency_m2m). Any custom logic previously using the original fields will need to be updated to reference the “parent” and “child” fields accordingly. This re-parenting process will occur automatically, as scheduled post the Yokohama upgrade. Please refer to the table below to estimate the impact time for customers. The FSM engineering team gathered these metrics through test runs on internal instances.
