Hello, I understand that you need to upgrade both versions of Perfex CRM (2.8.4 and 2.9.3) to the latest stable release while preserving all your existing customizations. My approach will involve a thorough diff and code analysis to identify modifications, refactoring customizations into separate modules to minimize future conflicts, and implementing database migrations to ensure data integrity.

Additionally, I will manage the project using Git for version control, ensuring that customizations and official releases are handled in separate branches. I'll also develop a CI/CD pipeline for automated testing and deployment across multiple sites. What specific custom enhancements need to be detailed at project initiation? Thanks, Muhammad Awais

Hello, I can upgrade your Perfex CRM to the latest stable version while ensuring no data loss and maintaining all customizations. I’ll back up your current instance, migrate safely, and then test all modules (invoices, leads, projects, etc.) to confirm everything runs smoothly. Performance tuning will also be applied so the CRM works faster and more reliably after the upgrade. Questions: – Do you have any custom modules or code changes in your current CRM that need to be preserved during the upgrade? – Should I set up a staging environment to test the new version before deploying live? – Do you also want me to optimize the hosting/database setup for better speed along with the upgrade?
