Hi. We had purchased Brooklyn 4.9 back in 2018. We want to know if Brooklyn v4.9 would support WP v5.0 or v5.6 or not. Secondly, what may be key differences between our Brooklyn v4.9 of 2018 and the current latest Brooklyn 4.9.X? Is the upgrade advisable and what may be the procedure to upgrade from our v4.9 to latest v4.9.X? Cost involved for this upgrade? Thanks.
