The "Sarah Jane Adventures" ended as of Series 5 which was only half complete. There were plans to bring Ace back in Series 6 and there was also a possibility of the series rebooting itself to a new location but because the series was suspended during mid production of Series 5, there's no certainty of what would happen next. After the events of The Battle of Bannerman Road, Sarah Jane would have either stayed on Bannerman Road or left for new adventures in Foxgrove which was previously seen in Series 2 (The Temptation of Sarah Jane Smith). The Battle of Bannerman Road (Series 5 finale) had a bunch of ideas and developments that were planned out but the episode itself never reached script form which means there are several possible outcomes of where the series could have gone but it would all depend on how Series 5 draws its conclusion.
