So, my solution to elasticsearch issue was to delete the index while on 6.8
curl -XDELETE 'http://localhost:9200/*'
update to 7.x and recreate index again.
zammad run rake searchindex:rebuild --trace
** Invoke searchindex:rebuild (first_time)

@MrGeneration do you know why i cant see all closed tickets in Ticket Overview? From today, i can see that there should be more closed tickets in this list (+15 Tickets) but there is one day off now (11.01. instead of 12.01.)
