# 4.65
As of Cognigy.AI 4.65.0, the Single Replica Redis setup is deprecated and replaced with Redis in High Availability (HA) Mode. For on-premises installations, before upgrading to Cognigy.AI 4.65, ensure that you migrate according to the [Redis: Single Replica to Redis HA Migration](https://docs.cognigy.com/ai/installation/migration/single-replica-redis-to-redis-ha-migration/).
As of release 4.65, the Agent Assist services have been fully integrated into the `cognigy-ai-app` Helm chart. This integration implies that the services provided by this Helm chart will be incompatible with versions 4.65 and onwards of the Cognigy.AI platform. Users must migrate to the new chart to continue receiving updates and support.
For detailed instructions, follow the [migration guide](https://docs.cognigy.com/agent-copilot/installation/migration/agent-assist-to-cognigy-ai-helm-chart-migration/).
Note that the `agent-assist-genesys-notifications-forwarder` will no longer be compatible with release 4.64 and earlier versions, as it now requires integration with RabbitMQ. Users are advised to plan their upgrade strategies accordingly to ensure smooth transitions and continued functionality.
As of Cognigy.AI 4.60.0, the old NLP services are deprecated. We will only provide bug fixes for the old NLP services if they are critical. The full removal of the old NLP services is planned for Cognigy.AI 4.64.0. After this release, the old NLP services will no longer be available. To migrate to the new version, refer to the [Cognigy NLU: from V1 to V2](https://docs.cognigy.com/ai/installation/migration/from-nlu-v1-to-v2-migration/) guide.

#### Cognigy.AI + Insights
##### Deprecation of Single Replica Redis
Starting from Cognigy.AI release 4.65,
the Single Replica Redis setup is deprecated and replaced with Redis in High Availability (HA) Mode.
If you are using on-premises installations,
make sure to perform the [Redis: Single Replica to Redis HA Migration](/ai/administer/installation/migration/single-replica-redis-to-redis-ha-migration) guide before upgrading to Cognigy.AI 4.65.
##### Knowledge AI Data Migration to MongoDB
Added a job to migrate Knowledge AI data from Weaviate to MongoDB. This job is enabled by default. To continue using the Knowledge AI feature, it's important not to skip this release.
Note that this job can be disabled if you have not yet purchased a license to use Knowledge AI. Refer to the snippet below, which can be configured in `values.yaml`. To disable it, set `enabled: false` as shown in the snippet. This job is temporary; once the migration is complete, it can be disabled.
```yaml theme={null}
migration:
kaiEmbeddingMigration:
enabled: false
# hooks: post-upgrade
# hookDeletePolicy: "before-hook-creation"
# image: cognigy.azurecr.io/kai-embedding-migration:380586885cf71f51c0ae9859cd134eca63de9cd3
# ttlSecondsAfterFinished: 100
```
##### Deletion or Migration Job for Legacy Endpoints
Added a default job to delete or move old endpoints that are no longer supported. This job removes all Google and Twilio Autopilot Endpoints.
Note that you need to disable this job for fresh installations in `values.yaml`.
To disable it, set `enabled: false` as shown in the snippet below.
This job is temporary; once the migration is complete, it can be disabled.
```yaml theme={null}
migration:
endpointDeletion:
enabled: false
# hooks: pre-upgrade
# hookDeletePolicy: "before-hook-creation"
# ttlSecondsAfterFinished: 900 # 15 minutes
# affinity: {}
