Vespene upgrades always preserve data through use of built-in database migrations.
The upgrade process for Vespene is as follows:
- Update the code on all nodes.
(2) Run “make migrate” on exactly one machine with database access to apply any database schema changes.
- Restart the webserver and worker processes
If using systemd and the production setup:
# systemd restart vespene.service
If not, just stop supervisord and restart it
(4) Make sure everything is happy by logging into the interface and running a build or two. Make sure it is successful.
