Upgrading from v5.31 to v5.37 should take roughly the same amount of time as upgrading from v5.31 to v5.35, then upgrading v5.35 to 5.37. However, an upgrade directly from v5.31 to v5.37 could potentially take hours due to the database schema migrations required for v5.35. Review the :doc:`important-upgrade-notes` for all intermediate versions in between to ensure you’re aware of the possible migrations that could affect your upgrade.
