Pivotal Platform v2.8 Breaking Changes
Page last updated:
This topic describes the breaking changes you need to be aware of when upgrading to Pivotal Platform v2.8. For more information about important preparation steps you must follow before beginning an upgrade, see Upgrading Pivotal Platform.
There are no breaking changes in this release of Ops Manager.
See the following PAS breaking changes:
PAS v2.8 and later requires at least one CredHub instance. If the number of CredHub instances is set to 0, the deployment fails.
If you scaled the number of CredHub instances to 0 in PAS v2.7, check the number of CredHub instances in the Resource Config pane of the PAS v2.8 tile and increase to one or more instances before you apply changes for the upgrade.
For more information, see PAS Must Use At Least One CredHub VM in the PAS v2.8 Release Notes.
Syslog Adapters are not supported in PAS v2.8. If you disabled Syslog Agents on PAS v2.7.7, you must enable Syslog Agents before you upgrade to v2.8.x. If you do not enable Syslog Agents prior to upgrade, the upgrade fails in order to prevent potential log loss.
To enable Syslog Agents on PAS v2.7.7, do one of the following:
Go to the PAS System Logging pane. Select the Enable agent-based syslog egress for app logs checkbox.
See the following Pivotal Isolation Segment breaking changes:
.isolated_diego_cell.placement_tag is renamed
.properties.compute_isolation and includes three new inputs. This may impact your platform automation scripts.
.properties.compute_isolation contains the following inputs:
.properties.compute_isolation.disabledto disable compute isolation
.properties.compute_isolation.enabledto enable compute isolation
.properties.compute_isolation.enabled.isolation_segment_nameto add a placement tag for your Diego Cells when compute isolation is enabled
You must update any platform automation scripts that include
.isolated_diego_cell.placement_tag to use the new
.properties.compute_isolation name and inputs. You must either disable compute isolation or enable compute isolation and specify a placement tag with these inputs.
For more information, see and Compute and Networking Isolation in the Pivotal Isolation Segment v2.8 Release Notes.
For guidance on setting configuration values, see the Compute and Networking Isolation section of the Installing Pivotal Platform Isolation Segment topic.
In the Isolation Segment v2.8 tile, compute isolation and networking isolation must be configured or disabled simultaneously. In the Compute and Network Isolation pane, you can disable compute isolation by selecting Disable under Compute isolation. If you disable compute isolation, you must set Router sharding mode to No Isolation Segment. If Compute isolation is enabled and Router sharding mode is set to Isolation Segment only, the Isolation Segment tile fails.
Compute isolation is enabled by default. However, isolation segments do not require compute isolation. For more information, see Compute and Networking Isolation in the Pivotal Isolation Segment v2.8 Release Notes.
For more information about configuring or disabling compute and networking isolation, see the Compute and Networking Isolation section in the Installing Pivotal Isolation Segment topic.
There are no breaking changes in this release of PAS for Windows.
