i need to migrate my current mattermost server v7.8 ( postgresql 12, ubuntu 18.04) to a new server ubuntu 22.04. the current installation is based on the tarball method.
now of course i would like to use the mattermost omnibus installation method on the new server to hopefully have less hassle with maintaining the installation in the future.
but first, i have some questions that i hope someone can answer.
- what would be the best way to migrate the existing data to the omnibus installation?
- is there a way to configure omnibus to only update the current extended support release?
