5-Step Seamless Rollout Checklist
Proven deployment protocol tested across thousands of architectural and manufacturing firms1
Import Corporate Templates (.DWT) & Plot Styles (.CTB / .STB)
Copy your existing corporate title blocks, standard layers, custom fonts (SHX/TTF), and pen table plotters (.ctb) directly into GstarCAD's Support and Plotters directory. Everything renders pixel-for-pixel identically.
2
Load Custom AutoLISP & Automation Scripts (.LSP, .DCL)
Use the APPLOAD command to load existing AutoLISP routines. Add high-frequency routines into the Startup Suite. GstarCAD's robust LISP engine natively handles Visual LISP activeX extensions and DCL interfaces.
3
Set Up Network Floating License Server (Optional)
For multi-user firms, install the GstarCAD Network License Manager on your local server. Dynamically distribute concurrent licenses across your team, maximizing license utilization without paying per user.
4
Parallel Pilot Testing
Have a pilot team of 2-3 senior designers run real-world production projects on GstarCAD for two weeks. Verify drawing interchange with external consultants and contractors.
5
Full Production Deployment & License Liberation
Roll out GstarCAD firm-wide. Terminate costly recurring subscriptions, gain complete license legal compliance, and enjoy uninterrupted CAD productivity for years to come.

30-Day Enterprise Zero-Downtime Migration Roadmap
Proven 4-stage methodology used by 500+ seat AEC design institutes and manufacturing plants
Week 1 · Stage 1
Technical Pilot & DWG Fidelity Benchmark
Select 5–10 power users across drafting disciplines. Test your heaviest production DWG files (Xrefs, dynamic blocks, annotative scales, sheet sets) and verify bidirectional save fidelity with external AutoCAD contractors.
Week 2 · Stage 2
Workspace, CTB & LISP/GRX Plugin Audit
Migrate custom command aliases (acad.pgp → gcad.pgp), ribbon .cuix files, .ctb/.stb plot style tables, .shx font directories, and in-house AutoLISP / .NET / GRX automation scripts.
Week 3 · Stage 3
Floating License Server & Silent MSI Rollout
Deploy the Gstarsoft Network License Manager (GLM / FlexNet) on your Windows or Linux server. Push silent MSI packages with pre-mapped network template paths via Active Directory GPO or SCCM.
Week 4 · Stage 4
Subscription Retirement & Skill Certification
Retire up to 80–90% of expiring AutoCAD annual subscriptions while retaining a minimal hybrid pool if required by specific legacy contracts. Onboard drafters via GstarCAD Skill Certification.
