Hello, I am trying to apply suggested patches but after applying some python error codes do not allow neutron services to start. Since my python skill is poor, I wonder if that patches are for python3. I am on centos 7 and (probably???) patches are for centos 8. I also wonder if it possible to upgrade a centos 7 train to centos 8 train without reinstalling all nodes. This could be important for next release upgrade (ussuri, victoria and so on).
