Pre-Update Checklist

Before proceeding with any update, complete the following checklist:

1. Backup Your Environment

   Create complete backups of your client-managed databases and configurations.

   # Back up MongoDB data
   mongodump --uri="mongodb://username:password@hostname:port/database" --out=/path/to/backup/mongo
   
   # Back up Elasticsearch/OpenSearch
   elasticdump --input=http://elasticsearch:9200/index --output=/path/to/backup/elasticsearch.json
   
   # Back up Redis
   redis-cli -h redis-host -a password --rdb /path/to/backup/redis.rdb
   
   # Back up S3 storage
   aws s3 sync s3://your-prisme-bucket /path/to/backup/s3-data
   

   See the Backup & Restore page for detailed instructions.

2. Review Release Notes

   Carefully review the release notes for the target version to understand:

   • Changes to Helm charts
   • Terraform module updates
   • Database schema changes
   • Required infrastructure modifications

   Release notes are available in the Prisme.ai customer portal and within the release artifacts.

3. Check System Requirements

   Verify your infrastructure meets the requirements for the new version.

   System Requirements Check

   # Run the Prisme.ai compatibility check
   kubectl apply -f https://raw.githubusercontent.com/prisme-ai/compatibility-check/main/verify-environment.yaml
   
   # Check results
   kubectl logs job/prisme-compatibility-check
   

   Pay special attention to:

   • Kubernetes version compatibility
   • Node resource availability
   • Database version requirements
   • Storage capacity
4. Update Terraform Modules

   If you’re using Terraform for infrastructure management, update your modules to the versions compatible with the new Prisme.ai release.

   # Update Terraform module versions in your .tf files
   
   module "prisme_platform" {
     source  = "prisme-ai/platform/aws"
     version = "x.y.z"  # Update to match your Prisme.ai target version
     
     # Your existing configuration...
   }
   
   # Run terraform plan to validate changes
   terraform plan
   
5. Prepare Rollback Plan

   Document a detailed rollback plan in case issues occur during the update.

   Your rollback plan should include:

   • Specific commands to restore databases from backup
   • Helm rollback commands
   • Terraform destroy/apply commands for affected resources
   • Recovery time objectives
   • Verification steps after rollback

Update Process

Helm Chart Updates

1. Update Helm Repository

   Refresh your Helm repository to get the latest charts.

   helm repo update prisme
   
2. Review Chart Values

   Compare your current values with the new chart’s default values to identify changes.

   # Get current values
   helm get values prisme-core -n prisme-system > current-values.yaml
   
   # Compare with new chart defaults
   helm show values prisme/prisme-core --version X.Y.Z > new-defaults.yaml
   
   # Use a diff tool to compare
   diff current-values.yaml new-defaults.yaml
   
3. Upgrade Core Components

   Update the core Prisme.ai components first.

   helm upgrade prisme-core prisme/prisme-core --version X.Y.Z \
     -f values.yaml \
     --namespace prisme-system
   

   The core components handle compute operations and must be updated before product modules.

4. Update Product Modules

   After the core is updated, upgrade each product module.

   # Update AI SecureChat
   helm upgrade prisme-securechat prisme/prisme-securechat --version X.Y.Z \
     -f securechat-values.yaml \
     --namespace prisme-system
     
   # Update AI Knowledge
   helm upgrade prisme-knowledge prisme/prisme-knowledge --version X.Y.Z \
     -f knowledge-values.yaml \
     --namespace prisme-system
     
   # Repeat for other product modules: AI Store, AI Builder, AI Governance, etc.
   
5. Monitor Update Progress

   Watch the deployment progress to ensure all pods are successfully updated.

   kubectl get pods -n prisme-system -w
   
6. Verify Connectivity to External Databases

   Ensure all services can connect to your managed databases.

   # Check MongoDB connectivity
   kubectl exec -it -n prisme-system deploy/prisme-api -- mongosh --eval "db.adminCommand('ping')"
   
   # Check Elasticsearch/OpenSearch connectivity
   kubectl exec -it -n prisme-system deploy/prisme-api -- curl -s elasticsearch:9200
   
   # Check Redis connectivity
   kubectl exec -it -n prisme-system deploy/prisme-api -- redis-cli -h redis-host ping
   

Terraform Updates

1. Update Terraform Provider Versions

   Ensure your Terraform providers are compatible with the new Prisme.ai version.

   terraform {
     required_providers {
       aws = {
         source  = "hashicorp/aws"
         version = ">= 4.0.0"
       }
       kubernetes = {
         source  = "hashicorp/kubernetes"
         version = ">= 2.10.0"
       }
       helm = {
         source  = "hashicorp/helm"
         version = ">= 2.5.0"
       }
     }
   }
   
2. Update Prisme.ai Terraform Modules

   Modify your Terraform configuration to use the updated Prisme.ai modules.

   module "prisme_platform" {
     source  = "prisme-ai/platform/aws"
     version = "X.Y.Z"  # Match your target Prisme.ai version
     
     # Your configuration...
   }
   
   module "prisme_databases" {
     source  = "prisme-ai/databases/aws"
     version = "X.Y.Z"  # Match your target Prisme.ai version
     
     # Your database configuration...
   }
   
3. Apply Infrastructure Changes

   Run Terraform plan and apply to update your infrastructure.

   terraform init -upgrade
   terraform plan
   terraform apply
   

   Review the plan output carefully to understand what resources will be modified, created, or destroyed.

4. Update Helm Charts Through Terraform

   If you’re managing Helm releases via Terraform, update those resources as well.

   resource "helm_release" "prisme_core" {
     name       = "prisme-core"
     repository = "https://charts.prisme.ai"
     chart      = "prisme-core"
     version    = "X.Y.Z"  # Match your target Prisme.ai version
     namespace  = "prisme-system"
     
     # Your values...
   }
   

Database Compatibility Considerations

MongoDB / Compatible

• Recommended version: 4.4+
• Required indexes will be created automatically
• Schema migrations happen on startup
• Connection string format: mongodb://username:password@host:port/database

Elasticsearch / OpenSearch

• Elasticsearch 7.10+ or OpenSearch 1.3+
• Check index mappings compatibility
• Some updates require reindexing
• Set elasticsearch.existingUrl in values.yaml

Redis

• Redis 6.0+ recommended
• Used for caching and message queuing
• Persistence configuration recommended
• Cluster mode supported in Prisme.ai v3.2+

Object Storage (S3)

• S3-compatible storage required
• Used for document storage
• Configure using storage.s3.* parameters
• Verify bucket permissions after updates

Post-Update Tasks

After completing the update, perform these essential post-update tasks:

1. Verify Database Connectivity

   Ensure all services can connect to your managed databases.

   # Check from a pod within the cluster
   kubectl exec -it -n prisme-system deploy/prisme-api -- curl -s <internal-elasticsearch-url>:9200
   kubectl exec -it -n prisme-system deploy/prisme-api -- mongosh --eval "db.adminCommand('ping')"
   
2. Run Database Optimization Tasks

   Optimize database performance after the update.

   # Run MongoDB index optimization
   kubectl exec -it -n prisme-system deploy/prisme-api -- node /app/scripts/optimize-indexes.js
   
   # Run Elasticsearch optimization
   kubectl exec -it -n prisme-system deploy/prisme-api -- node /app/scripts/optimize-indices.js
   
3. Verify Product Functionality

   Test each Prisme.ai product to ensure they work as expected:

   • AI SecureChat
   • AI Store
   • AI Knowledge
   • AI Builder
   • AI Governance
   • AI Insights
4. Check Resource Utilization

   Monitor resource usage to ensure the system is functioning efficiently.

   # Check pod resource usage
   kubectl top pods -n prisme-system
   
   # Check node resource usage
   kubectl top nodes
   

Rollback Procedure

If you encounter critical issues after an update:

1. Roll Back Helm Releases

   Use Helm rollback to return to the previous version.

   # List Helm release history
   helm history prisme-core -n prisme-system
   
   # Rollback to previous revision
   helm rollback prisme-core [REVISION] -n prisme-system
   
   # Repeat for other releases
   helm rollback prisme-securechat [REVISION] -n prisme-system
   
2. Restore Databases

   If necessary, restore databases from your pre-update backups.

   # Restore MongoDB
   mongorestore --uri="mongodb://username:password@hostname:port/database" /path/to/backup/mongo
   
   # Restore Elasticsearch/OpenSearch
   elasticdump --input=/path/to/backup/elasticsearch.json --output=http://elasticsearch:9200/index
   
   # Restore Redis
   redis-cli -h redis-host -a password SHUTDOWN SAVE
   # Copy backup RDB file to Redis data directory
   
   # Restore S3 data if needed
   aws s3 sync /path/to/backup/s3-data s3://your-prisme-bucket
   
3. Revert Terraform Changes

   If you used Terraform for the update, revert to the previous state.

   # Revert to previous Terraform state
   git checkout [previous-commit] terraform/
   terraform plan
   terraform apply
