Upgrade Notes

Cloud Upgrade

  • Cloud upgrade is supported from v1.3 as well as v1.4
  • Terraform version 0.14.5 is recommended for orc8r upgrades. Current terraform scripts are not compatible with terraform 0.15.0.
  • Due to the database unification for NMS and orc8r, orc8r upgrades have two pre-requisite tasks:
    • DB Migration - Please refer to instructions on GitHub for the migration. Note that the migration MUST happen prior to executing the terraform upgrade.
    • Terraform sanitization - references to NMS DB need to be removed from the file. Further, the dialect for the orc8r DB needs to be specified. Please refer to the example located here.
  • Please note that the orc8r file should reference orc8r helm chart version - 1.5.21
  • Starting with v1.5, a new pre-defined alert has been added to raise a critical alert when excessive duplicate attach requests are received at the gateway or if the SCTPD service restarts multiple times (this was introduced in v1.4). In order to start receiving these alarms, it is necessary to click on the β€œSync Pre-Defined alerts” in the NMS window for every network defined in the orc8r. Syncing the alerts once on the NMS does not replicate the behavior to other networks managed by the same NMS.
