Thank you @MrGeneration for you quickly response.
Só I was using the version 3.6 and to we migrate without breaking the system I userd:
apt install zammad=4.1.0
apt install zammad=5.1.0
apt install zammad=6.0.0
apt install zammad=6.1.0
apt install zammad=6.2.0
apt install zammad=6.3.0
After all of this steps I could use the zammad.
I didn’t realize that the users weren’t showing up
For example, I have a list of over 1000 users, but when I list the users without selecting a role or try to search for any name other than mine, it doesn’t find it.
And my user list is reduced to a maximum of 50 users.
If I run this command I could find my all users:
zammad run rails r 'puts User.pluck(:id, :firstname, :lastname, :email)' > /home/xxx/usuarios.txt
