I want to migrate from my 3.1.10 system to 3.3.4 ( new server). I have tried the database dump, but i see it is not working properly i.e. in package manager on 3.3.4 with database restored from 3.1.10 , i am still packages 3.1.10 version that is from the old system.

I only intend to keep the tickets data, CMDB and related data.

Thanks
