Quantum Grizzly Upgrade Paths

  1. 1. Openstack Grizzly SummitQuantum Upgrade Paths San Diego, California Tuesday, October 16th
  2. 2. Summary• Problem statement:THERE IS NO WAY TO PERFORM ANY KIND OFUPGRADE ON QUANTUM• Goal:MAKE SURE THAT FOR GRIZZLY QUANTUM HASAN UPGRADE STORY
  3. 3. Upgrade Path 1:• From Quantum X to Quantum Y• DB Upgrade procedure – SQL alchemy migrations – For extension too • Handle properly plugin-specific extensions• Plugin specific upgrade operations – If needed, can be performed with plugin-specific procedure after db upgrade• MUST target Grizzly – possibly milestone #1 or #2
  4. 4. Upgrade Path 2• From Nova-network to Quantum – Extract information from nova DB – Create Quantum logical model – Rebuild networks (fairly hard according to requirements) • Need to exactly scope what we want to achieve when migrating from nova-network• It would be awesome to have something for it in Grizzly!
  5. 5. Upgrade Path 3• From Quantum Plugin A to Quantum Plugin B – Do we have a use case for this? – If yes, Should it be plugin-specific?• If a use case is agreed for it, can be implemented post Grizzly
