Hello,

I have a 3-nodes PXC5.7 cluster running on Centos 8 servers managed by Clsuter Control (ver 1.8.2)  and need to upgrade it to PXC 8.0.

What's the recommended procedure ?

  Hi Rosario Esposito

  In that regard, you have to upgrade it manually as CC does not support major upgrade. You should do first in a test environment with exact environment and data as your prod. Write down the procedures you have took during the upgrade process. You can reference your questions by reading this blog https://severalnines.com/database-blog/tips-upgrading-percona-xtradb-cluster-80. It will guide you from what to do and where to go.
