Upgrading Kopia to v0.9

Kopia v0.9 adds support for several new features thanks to a brand-new index format.

If your repository was created in a version older than v0.9, please follow the steps below to upgrade.

Notes

• After the upgrade, kopia v0.8 and earlier will not be able to open the repository anymore.

• It is very important to perform repository upgrade without other clients accessing repository to avoid data loss.

Upgrade Process

1. Disconnect all but one kopia clients:

• using CLI run

$ kopia repository disconnect

• using KopiaUI, click Repository | Disconnect.

2. Upgrade all kopia executables to >=v0.9.0-rc1

3. Using the remaining connected kopia client, run:

$ kopia repository set-parameters --upgrade

4. Verify upgrade by:

$ kopia repository status

You should see Format version: 2

5. Reconnect kopia clients that were disconnected in step 1

After upgrade all new v0.9 features will be supported except password change.
