I'm new at this forum. I looking for some information about TC. I need make upgrade TC 5.2.3 to the latest. Import data from backup.zip made with no problem. After update conluence from 5.2,3 to 7.2.1 the team calendar doesn't work . I think that problem is at the database side . Is I made install TC - TC made new column at database ? Maybe columns are different between 5.2.3 and 7.2.1 version??? I have an idea to remove calendar , uninstall TC application and try to delete TC columns from database. After upgrade will make install TC 6.0.47 . Is my idea is correct? I need some help for this issue.
Many thanks for any help
