Module-Specific Upgrade Notes

Critical Modules Requiring Special Attention

POS Ecosystem

pos_utils - Core utility module for all POS functionality - 10+ modules depend on this - Test thoroughly with all POS operations

pos_promotions - Integrated with sale_coupon - Check promotion calculation logic - Verify discount application

pos_rest_api - External integrations depend on this - Maintain API compatibility - Document any endpoint changes

Inventory & Warehouse

cnf_stock_scheduler - Parallel processing critical for performance - Uses job queue heavily - Monitor resource usage

merp_* (VentorTech Suite) - Third-party warehouse management - Contact VentorTech for v18 version - Critical for warehouse operations

stock_inventory_queued - Performance optimization module - Depends on queue infrastructure - Test with large inventory counts

Accounting Modules

account_3_way_update - Complex matching logic - Test with real purchase scenarios - Verify all three-way match cases

account_payment_cpa005 - Canadian EFT payments - Critical for vendor payments - Test with bank file generation

cnf_account_loc_costcenters - Foundation for cost tracking - 18 modules depend on this - Cannot break this module

Third-Party Integrations

connector_cnf_inventory - Shows warnings but passes tests - External system integration - Document all API changes

muk_rest - REST API framework - Many modules use this - Maintain backward compatibility

Modules Under Investigation

Product Information Modules

product_gs1 - GS1 barcode standards - May need industry spec review - Check scanner compatibility

product_nutrition - Nutrition label requirements - Verify regulatory compliance - Test label generation

product_lnhpd - Natural health products - Canadian regulatory requirement - Needs domain expert review

UI/UX Modules

cnf_cart_customizations - Custom HTML in cart - Check XSS vulnerabilities - Verify responsive design

sticky_header_tree_and_form_view - UI enhancement - Test on all browsers - Check mobile compatibility

Deprecated Module Candidates

Currently Unused Modules

theme_clarico_vega & related - Marked as not used - Consider native v18 themes - Plan website redesign

emipro_theme_* modules - All marked as unused - Safe to deprecate - Remove dependencies first

shopify_ept - eCommerce integration - Currently not used - Keep if future plans exist

Module Pairs & Groups

Tightly Coupled Modules

Queue Job Infrastructure 

queue_job ← cnf_queue_job ← [many modules]
Must upgrade together

Component Framework 

component ← component_event ← connector
Framework modules, upgrade as unit

Document Management 

document_page ← document_page_approval
              ← document_page_group
              ← document_page_tag
Can be upgraded independently

Performance Critical Modules

These modules directly impact system performance:

  1. cnf_stock_scheduler - Parallel processing
  2. stock_inventory_queued - Async inventory
  3. cnf_queue_job - Job queue infrastructure
  4. cnf_performance_improvements - Various optimizations

Security Sensitive Modules

Require extra security review:

  1. account_payment_cpa005 - Payment processing
  2. pos_rest_api - External API access
  3. muk_rest - REST framework
  4. two_factor_otp_auth - Authentication
