My production cluster is running 3.22. I am looking at skipping 3.23 and upgrading straight to 4.01 when it comes out.
So my questions are:
Should I wait for 4.0 or SHOULD upgrading to 3.23 be a necessary step to jump to 4.0.
Are there any database changes coming in 4.
During upgrade process what happens if I upgrade all my servers and then they don’t want to work after reboot. Is there a way to upgrade 2 out of 4 and then 3 and 4.
Yes, I will probably wait til 4.01 before upgrading rather than 4.0
So looking to have upgrade plan. Your genius input appreciated.
