Upgrade Workflows

Fusion Data Foundation recognizes two types of upgrades: Z-stream release upgrades and Minor Version release upgrades.

While the user interface workflows for these two upgrade paths are not quite the same, the resulting behaviors are fairly similar. The distinctions are as follows:

For Z-stream releases, Fusion Data Foundation will publish a new bundle in the IBM catalog source. The OLM will detect this and create an InstallPlan for the new CSV to replace the existing CSV. The Subscription approval strategy, whether Automatic or Manual, will determine whether the OLM proceeds with reconciliation or waits for administrator approval.

For Minor Version releases, Fusion Data Foundation will also publish a new bundle in the IBM catalog source. The difference is that this bundle will be part of a new channel, and channel upgrades are not automatic. The administrator must explicitly select the new release channel. Once this is done, the OLM will detect this and create an InstallPlan for the new CSV to replace the existing CSV. Since the channel switch is a manual operation, OLM will automatically start the reconciliation.

From this point onwards, the upgrade processes are identical.
