Artifacts:

In addition to our charms, we also released to 6/stable other artifacts, namely:

Artifact Version Sources (github) License
Snap: Charmed MongoDB 8.0.10-4 charmed-mongodb-snap Apache 2.0
Rock: Charmed MongoDB 8.0.10-4 charmed-mongodb-rock Apache 2.0

Major version upgrade path from 6/stable to 8/stable:

To migrate from “Charmed MongoDB 6” to “Charmed MongoDB 8”, it is imperative that the transition happens through backup and restore, and through the artifacts located in an intermediary track: 8-transition/edge (which contains the mongodb 7 binaries).

The 8/transition track will remain in edge (on the 24.04 base) and should only be used for the transition from 6 to 8.

The major version upgrades procedure is documented in the guide can be found here.

In short, the transition path can be described as such:

  • MongoDB 6/stable -> MongoDB 8-transition/edge -> MongoDB 8/stable.

Note:

The mongos documentation will soon be migrated from charmhub to the read the docs project.
