Description Yolanda Robla 2017-11-02 07:58:47 UTC
Description of problem:

For fast forward upgrades, we have some very specific needs for telcos. Specially, it is very important to consider the maintenance window. We have a limit of 4 hours per window. In this window we need to do several tasks:
- take backup
- start the upgrade task
- test
- rollback if something went wrong

This needs to be considered for all the parts of the process. Specifically, we have an important need in terms of upgrading the computes. Computes need to be upgraded in batch, and also we need the ability to control the order of the upgrades and reboots.

Comment 1 Yolanda Robla 2017-11-02 12:11:47 UTC
More requirements:
- data plane needs to be 100% up
- add the ability to control the order of reboots in the minor update step
- add the ability to provide hooks, after minor updates, to be able to deal with ovs version upgrade problems

Hey Maria, I'm assigning this to you for further discussion.

Hi Anjali

AFAIK, this BZ is on Dev, why is it on QA?

Verified 

FFU was manually done from 10z10 (puddle ID - 2019-01-03.2) to 13z5 (puddle ID - 2019-02-15.1)
Constraints were that default roles for compute were used.
