Applications running on isolated_diego_cells
and windows_diego_cells
using TCP routes will experience downtime during upgrades with certain IST and TAS version combinations. Routes for apps using TCP Routing will not work until the TAS tile is updated to a fixed version.
Any applications making use of data services from the below tiles will experience downtime during upgrades, unless TAS is upgraded to a fixed version prior to updating the data services tiles. Applications using data services via TCP Routing will fail until the TAS tile is updated to a fixed version.
You will be affected if you are using TCP Routes and Isolation Segments (IST) or Tanzu Application Service for Windows (TASW) and are currently on one of these versions of Tanzu Application Service for VMs (TAS):
And are upgrading to one of these tile versions:
You will be affected if you are currently on one of these versions of Tanzu Application Service for VMs:

Upgrade TAS to at least the below versions, before upgrading any IST, TASW, or Data Service tiles:
Upgrading TAS first will ensure that your TAS tcp_router VMs are upgraded with the preventative fix prior to the affected tile VMs being updated.
The upgrade to a fixed version of TAS and new version of IST, TASW may be done in the same Ops Manager deployment.
