    *[ERROR] InnoDB: Upgrade after a crash is not supported. The redo log was created with MariaDB 10.4.16.* - this means that you tries to upgrade after unsuccesful server stop. Now you must revert to old version, recover the data and achieve normal server shutdown then upgrade the server. – Akina Dec 31 '21 at 12:11
  • @Akina i have reverted the old version and it works well but how can i recover the data?..i copied some of the data from the previous MySQL to the new one and i think that why there is an error..which data in the data folder should i copy – stephen waweru99 Dec 31 '21 at 12:27
