Important! Redis DB conversion is required.

Moira 2.4 has some structure changes in Redis DB. It will work fluently out of the box, but lazy triggers will still be checked every time on new metrics.

You can upgrade from moira 2.2 or 2.3 using corresponding flag in --from-version variable.

moira-cli --config=/etc/moira/cli.yml --update --from-version=2.2/2.3

If you would like to downgrade back to Moira 2.2 or 2.3, you should run CLI-converter.

moira-cli --config=/etc/moira/cli.yml --downgrade --to-version=2.2/2.3

Both cases imply usage of Moira-Cli v.2.4, you can find it on Release Page.
