Hi, I'm trying to migrate my 7.4.4 (test environment) instance to the newer LTS 8.4.5. I have 3 main errors: 1) During the startup I get errors about missing ldap classes (I'd like to resolve later, I think it depends on some missing plugin, right?) 2) When I access as Admin user (after the distribution installation wizard phase) , the drawer menu has only one voice (Application Index) under "Home", where are the other voices (Administration,indexes...)? 3) If I try to go to the preferences page with the old url I can see the page but I also see strange icons on the right (maybe something went wrong during files replacement? I set always "replace files with newer ones" during the distribution wizard phase). If the problem is related to the environment data folder, I didn't use a fixed one (I'm in test environment) I used the tomcat's temp directory (that I deleted before the installation). I didn't have important files to save so I thought that I could replace them easily with the new installation. Thank you for support.
