Running on Virtual Machine/Bare Metal

Assume OneDev is installed at /opt/onedev, stop OneDev by running command /opt/onedev/bin/server.(sh|bat) stop
Make sure database server is up and running if you are using external database
Extract new OneDev version to a separate folder, say /path/to/new-onedev

Run below command to perform the upgrade:

/path/to/new-onedev/bin/upgrade.(sh|bat) /opt/onedev

/opt/onedev will be upgraded and you may launch it to check if things are in order
You may remove /path/to/new-onedev afterwards if everything is fine

note

If you are running a cluster, you will need to repeat above steps for each OneDev server in the cluster
