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.

Important! Redis DB conversion is desirable.

Moira 2.3 has some structure changes in Redis DB.
It will work fluently out of the box, but we recommend you to run converter once Moira is updated.

moira-cli -update --config=/etc/moira/cli.yml

/etc/moira/cli.yml

redis:
  host: localhost
  port: "6379"
  dbid: 0
log_file: stdout
log_level: debug

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

moira-cli -downgrade --config=/etc/moira/cli.yml

Both cases imply usage of Moira-CLI v.2.3, you can find it on Release Page.
