I have migrated the zabbix 2.2 from 4.4 and the content is not shown to me

[afabra]

Hello, I have done a migration of zabbix 2.2 to 4.4, but once migrated, I am not shown the previous zabbix content.

in the logs it does not show any error, the zabbix is shown to me as if it were a new installation, but in the postgresql there is the content and configuration of the previous zabbix and the zabbix is connected in the database.

What I can do?

thanks

Andreu
