[Docs][Upgrade] Update Upgrade Guide to recommend VMs power cycle
Last modified: 2017-08-13 23:44:19 EDT
Description of problem:
we recommend to power cycle all VMs after changing cluster level soon.
but we do not have such info in Upgrade Guides.
Michal Skrivanek noted the power cycle in a thread with following
note that for migration improvements to be effective (4.0 feature) the
cluster level would need to be further updated to 4.0 compatibility
and migration policy would need to be changed from “Legacy” then. This
4.0 cluster update need to happen only AFTER all the former originally
3.5 VMs are power cycled and running properly as 3.6 VMs! Otherwise
the same migration configuration tweaks may need to be applied (I
suppose it’s mainly the bandwidth speed, but pending confirmation)
Version-Release number of selected component (if applicable):
Michal, could you prepare a text for this recommendation explaining
reasoning for this please?
the text is in bug 1356027 doc text
Assigning to Byron for review.
Implemented review comments and merged.
