Every environment upgrade can contain new features and bug fixes. The Collibra Platform data structure can change during an upgrade, or that existing content will be migrated as well. This is an irreversible action, unless you restore a backup from your environment prior to the upgrade.
The proposed date and time of an upgrade is communicated to you through email, at least two weeks prior to the planned upgrade. These upgrades are done over the weekend to avoid any impact on the users.
Within these two weeks, you can request to delay this upgrade by replying to the email. You can propose a later date and time, up to two months after the initially proposed upgrade date.
Note If you don't reply to our upgrade proposal, we assume that you approve, and we will upgrade your Collibra Platform environment at the proposed date and time.
The downtime for an upgrade depends on the size and complexity of your Collibra Platform content.
After the upgrade to 2020.11, you have to upgrade the activity history. This is a one-time only action, subsequent upgrades don't require this extra step.
Important After an upgrade of your environment, verify if you have to upgrade your Jobserver. Check the release notes to know which Jobserver version you need. See the installation section for the upgrade steps.
