Description Paul Dwyer 2018-04-12 10:27:07 UTC
Document URL: 

Section Number and Name: 
Upgrading Cluster (probably both automated and manual upgrade sections)

Describe the issue: 
Engineering have suggested validate 3.7 storage migration the day before the upgrade using
oc adm migrate storage --include=* --loglevel=2

This would ensure some potential problems can be spotted early and can be resolved before going into outage window for upgrade to 3.9.

Suggestions for improvement: 
Include suggestion as per above.

This is a general suggestion applicable to all upgrades.

Comment 5 Ashley Hardin 2018-08-09 20:11:26 UTC
Work in progress: https://github.com/openshift/openshift-docs/pull/11484

Comment 6 Scott Dodson 2018-08-10 15:34:12 UTC
BTW, it's a good idea to run this migration prior to all upgrades whether it's a 3.y.z to 3.y.z+1 upgrade or 3.y 3.y+1 upgrade. Lets add this to 3.9 and 3.10 docs too.

For all, it's better to add "--config /etc/origin/master/admin.kubeconfig" for the command.
For pr 11484, seems no need to specify "3.7 ", refer to other two prs.
For pr 11505, miss "--confirm" for the command and wrong version of "3.7".
