Rough Country's current-state architecture maps a managed RemoteApp access layer, centralized identity and security controls, and dedicated SAP Business One workload infrastructure across Windows session hosts and SQL Server databases. Data flows from SAP session hosts through application and web service tiers to integrations with WMS, tax, payment, and eCommerce systems, with backup and recovery storage ensuring resilience. This architecture documents the baseline for DR1/DR2 review and identifies validation gaps in sizing, user concurrency, licensing, and integration readiness before cutover. Fork this diagram on Diagrams.so to customize for your SAP migration planning, add region-specific details, or extend with future-state replatforming scenarios. The open validation items highlight critical dependencies on HighJump/Acellos, Avalara/Avatax, and vendor coordination that must be resolved during the readiness phase.
